If u want to surf the internet fo free on Airtel Live, then what u'll need is the Teashark and UCWEB Fly v5.
I use both these programs & it is 100% working:D
I know most of You might know this:D
Download them from following Links.
Teashark_3versions.rar
UCWEB 5-1.jar
The first file contains 3 versions of Teashark.
Teashark v312, Teashark v411 & Teashark v419.
The latest version of Teashark i.e the Teashark v419 does not run on all phones.
So try which one of the three works for U guy's.
Teashark v419 used to work on my K550i before i CrossFlashed it to W610i.
Now it doesnt run on my phone, So i use Teashark v411 & it is 100% working.
