Steps to get 500 MB free 3G data on Airtel

Recently I came across this method which gives you access to free 500 MB of 3G data, on all types of Airtel (postpaid as well as prepaid).

Here's what you've got to do:

  • Go to the URL: where MobileNumber is your Airtel number.
  • They will send a One Time password to your above specified number, enter it on the site, and hit submit.
  • On the next page that opens, there would be a panel having "do more" at the bottom, hover your mouse over it and three options come. Select transaction details and note the URL of the page you're taken to. It would contain your msisdn number at the end. Copy it and replace it in the URL:

    where XXXX is your msisdn number obtained in the previous step.
  • When you open this URL, you'll get a page having a panel on the left and one image towards the right stating you'll get free 500MB of 3G data.
  • On opening this, you get a page asking for your alternate number and email ID. Enter these details and voila! You receive a message on your mobile confirming the same.


Hands on Android L Developer Preview

To everyone's surprise, Google announced the latest Android version, codenamed Android L, at Google I/O 2014. And to make things crispier, it also released a developer preview allowing developers to have a glimpse of what is about to follow. It is a major update after a long time and introduces many new visual as well as API level changes. According to Google, 5000 New APIs have been added to this L build.

It is currently available only for Nexus 5 and Nexus 7 2013 (WiFi only). And can be downloaded by going here. (If you are unable to install it, let us know in comments and we'll frame a step by step post on that as well.)

 We took it for a spin and here is what you can expect.

For people too lazy to read, here's a video hands on:

Boot Animation

Let us start with boot-animation which renders four dots swirling around and finally merging to form the word 'android' when the OS is loaded. Booting takes slightly longer time than Kitkat on Nexus 5. This might be because it is still in developer preview.

The home screen greets you with the same set of icons and UI as on Kitkat. The four major visible changes to the User Interface are in the notifications panel, Task Switcher, Lock Screen and the settings menu.

Material Design
Google has not yet released the new versions for different Google Apps. The only apps that currently follow the new material design are Phone Dialler, People (Contacts) and Calculator. All these 3 apps look really cool in material design.

The calculator application that follows the material design has vivid colours. The application also modifies the background colour of the notification bar. The advanced functions slide out from the right and the green background looks pretty nice. When an error happens during calculation, the application can also shift the colour of the notification bar, to reflect changes in state of the application.

Any application that is closed making use of the back or home button now suspends employing a new slide down animation. The animation is smooth and looks good.

Task Switcher

The task switcher is different from the previous versions that existed on Jellybean and KitKat. It features a tabbed page layout (similar to chrome mobile tabs), which is smooth and mentions the application name and icon. You can still slide it to the left or right to remove it from the list, but a close button at the top right end of every application tab may also come out to be handy. The feature of long pressing an app icon in the task switcher is now missing. It used to provide a direct short cut to go to the 'App Info' page of the selected app.

Notifications Panel

The notifications panel now has a stack layout which is pretty impressive but currently lacks the button for clearing all notifications which becomes a little tiresome. The toggles can be pulled down by pulling the notification bar and then taping on the top most bar.

You cannot interact with the notifications when the quick settings panel is pulled down.

Battery Saver

The battery saving mode introduced in Android L decreases the CPU and GPU clock speed. It also turns the brightness down. You can turn it on manually or set a threshold battery percentage below which the battery saver mode automatically kicks in. You may not desire to employ the phone all the time in battery saver mode as the phone becomes slower and most of the UI animations are also turned off.

Update(July 8th, 2014): I have been using this build for more than 10 days now and I actually feel that the battery performance is not very good without the battery saver mode. The battery run-time has reduced in Android L as compared to KitKat. The battery lasts long enough only if used in Battery Saver mode.

Settings Menu

The new settings menu is more or less the same with a different look and feel. You can now search inside the settings menu granting you an added advantage over navigating through the vast menu.

The WiFi and Bluetooth Toggles have been removed from the settings menu to give a cleaner look but I personally feel they should have been there.

Keyboard Layout

The keyboard is still the same with a new minimalistic layout. It performs the same way as the old one and I did not experience any troubles while typing. The sliding input feature is still available and it functions well.

Power Menu

The power menu currently has no other options except the power off button which is a little sad and I hope it is just in the developer preview. You can still boot into safe mode by holding on to the power off button.

Lock Screen

The lock screen by default shows all your notifications from the notification bar. You can simply tap to expand the notification or double tap to proceed inside the desired application. If you have set up security on your lock screen no personal information is revealed by the notification and it requires you to enter your pin, password or pattern before you can further interact with the notification.

On the lock screen you can swipe in from the right to open the camera, from the left to open the dialler app or just swipe up to unlock your device. All these transitions are quite smooth.

Do Not Disturb

Everyone would be familiar with the DND option but it was never available as a pre-installed feature on your android phone. Now all notifications can be blocked or they can be customized. You can block a notification from everyone, allow notifications from only starred contacts or all people in your contacts.

The DND Hours can also be customized if you are the one who requires a peaceful sleep at night without any disturbance. Of course the alarm would still ring even if your phone is in DND mode.

All this existed earlier in the form of third party apps but it is always better to have these things baked into the OS.  


Overall it is a nice, fluid and cool update. The animations are pretty. There are not many bugs that you will encounter except that the Cast Screen option does not retrieve nearby devices. The battery life appears to have improved a little bit with the battery saver option. The UI experience is smooth enough to get habituated to. The three navigation buttons have been altered to give a new look to the entire interface. The notifications can be turned off any time by making use of the Do Not Disturb Feature. Also the Gallery application has been removed and you are forced to use the Photos app.The lock screen is more interactive and useful than before. The only unstable aspect of the preview is that the battery is draining a bit faster, but that too is not a drastic fall. Rest everything seems to be working great as of now. Hope to see the materialistic design implemented in all applications soon to have an enriching experience. Apart from the flatter look, Google has ditched DALVIK runtime for ART, and has made it faster and efficient.

Update (July 8th, 2014): Some applications such as GrooveIP used for calling don't work. For people who don't know what GrooveIP is, it is an application that lets you make free phone calls to US and Canada. The call goes through in the application but no voice is heard.

Have you installed the preview as well? Let us know what you think and your experience in comments.

How To Backup Your Call Logs And SMS in Android

Android users have often faced the wrath of having the smart phone save call logs of only the past 30 days and every call made or received before this time span is removed from the device by default. If you are a person who uses texts on a regular basis, you might find your inbox messed up. And you feel like if there existed some method to back it all up automatically. And this post is going to help you with this problem.

Now a few of you would be thinking why not use Titanium Backup and similar applications for the task? Precisely for you people, they are paid and are available only for rooted Android devices. And you don't get searchable spreadsheets using them, unlike IFTTT.

What you need:

  • IFTTT (If This Then That) installed on your android device
  • A Google account (which you'd be having I assume)

This is what IFTTT looks like after installation:

Here is what you need to set up to automatically backup your logs and SMS's in Google Drive as Spreadsheets:

How to backup phone logs:

Run the application and create a new "recipe".

In order to backup all types of call logs, we create three separate recipes for :

  •  Missed Calls
  •  Received Calls
  •  Dialled Calls 

1. Select the channel for “IF” (by tapping the + button next to IF). In the list that appears, scroll and select “Android Phone Call” and tap the blue plus sign next to “Any phone call placed”.

2. Now, select the channel for “Then”. Scroll to select “Google Drive” and tap the blue plus sign next to “Add row to spreadsheet”.

3. Choose if you wish to receive notifications or not when the recipe runs. Hit Finish.

And its all done. From this point onwards, on every phone call made from your device, it will be automatically backed in a spreadsheet file in your Google Drive if it is connected to Internet, or the same will be done as soon as you connect to Internet.

Similarly, you can create recipes for received and missed calls, by choosing so in the first step.

How to backup text messages:

The procedure is similar to that of phone logs.The only difference being

You have to select the channel for “IF” as “Android SMS” in the first step.

Note: This method does not cover older messages that have already been received, but you may download and install "SMS Backup & Restore" from the Play Store and use it.

And you've just created your own backing up trick which will store all your logs and SMS in a spreadsheet forever (unless you decide to delete the sheets). Let us know your experience and any other alternatives that you use in comments.

How to download iOS 8 without having a developer account


It ain't a big news that Apple recently released the next huge update to its mobile operating system. And everyone has been talking  about it since the features were showcased at WWDC'14 . Just like the last year, people/companies who are registered developers for Apple only have the early access to the operating system. But don't worry. Even if you're not a developer, and wish to try iOS 8 out, we have you covered!

Thanks to, we no longer need to wait until Apple releases iOS 8 for those who aren’t registered developer’s for Apple.

Users can download iOS 8 by going to the following link :
(Note that files for some devices are still being uploaded.)

A couple of facts before you begin downloading:

1. iOS 8 would have lot of bugs and you may face troubles while using your phone.
2. Backup your phone before updating just in case there are problems later.

And just in case you forget, iOS 8 is compatible with:

  • iPhone 4s and later
  • iPad 2 and later
  • iPad Mini & iPad Mini with retina display
  • iPod Touch 5th Generation
Before beginning the process, do note that this process can be performed without the need of a UDID, that is, you can install iOS 8 on your device without using UDID. In other words you don't need a developer friend or you don't need to buy a UDID online via various websites. You can just install iOS 8 without UDID registration.


Step 1: Open iTunes.
Step 2: Connect your iDevice with Mac via USB .
Step 3: Restore your iPhone, iPad or iPod touch to iOS 7.1.1 via iTunes, then set it as a new iPhone.
Step 4: Hold SHIFT and left click on “Check for Updates” on iTunes, then locate the iOS 8 beta 1 folder which you downloaded above. Wait for few minutes and enjoy iOS 8

Using the Caps Lock Key as a shortcut to Cut Copy and Paste

The Caps Lock key on the keyboard is one of the least used keys and a pointless one too. Unless you are a person who likes screaming on people, you will agree to the above statement. People generally prefer using the shift button to make the letters upper case. You can instead map it to do more useful functions.

All you need is : a software named AutoHotKey (can be downloaded here)

Now that you have the software installed, lets get to creating a small macro! Create a file with extension ".ahk". You can name it anything you want it to be. Open it with a text editor, and copy the following code:

if (A_PriorHotkey <> “~CapsLock” or A_TimeSincePriorHotkey > 500)
KeyWait,  CapsLock
SendInput, ^c
SendInput, ^v
SendInput, ^x

Now all you need to do is to save this file and double click it to execute it and then you can use the Caps Lock button to Cut, Copy and Paste for you instead of turning the case of letters. Pressing shift and caps lock will act as cut, tapping caps lock once will act as copy and double tap will act as paste.

The problem with this snippet though is that you need to execute it every time you start windows, which is a problem. So let's put it into startup of the computer to avoid this hassle too! Here's how:
Navigate to: "C:\Users\[UserName]\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup" and paste the file you just created here.

Note: You can still toggle caps lock on and off if you really need to, by using the key combination of Windows + Caps Lock.

You can similarly do various fun stuff with other non useful keys of the keyboard and play with it. Do let us know your experience in comments!

How to log into various accounts on any website

Here's a chrome extension that allows you to sign into various accounts on any website without the need of having you to open incognito mode on your chrome. But you can use multiple profiles, you say? Yes you can, but who has got the time these days. We need to access everything at finger-tips these days and this extension is exactly what you need in that case.

This one's is similar to MultiFox add-on for Firefox, but somewhat easier to use. All you need to do is press the little button to the top right of the browser (after installing the extension). Clicking on the extension icon opens a new tab, which looks similar to a new tab but works like a tab in incognito mode. And in this tab, you can visit any website and start a new session altogether. Also the extension adds an option in the right click context menu of your browser using which you can "Open Page in New Account Tab" and the extension duplicates the site you are browsing allowing you to log into another account on the same site (same as before).

You can download the extension from the Chrome Store here: MultiLogin.

The extension adds a random number to every new tab you browse, which is unclear as to what the prefix is, and also you cannot remove this number. It's unclear why it exists, maybe to differentiate amongst tabs or something, but its a small price you need to pay, inconvenient it may be but worth the efforts of creating a new profile every time you need to log into various accounts on a site.

If you are using Firefox and are not aware of MultiFox, then it does the same thing. You can download it from here: MultiFox.
