Thanks for the help. The problem is, I use Debit Card in mChek. Online mChek works fine with Credit Card only, and not Debit Card. I am hunting between Banks & AirTel & mChek on this.
Recently, I found a converter online, which converts JAD file into APK. I tried, and it got installed in my XPERIA. But doesnt work properly though.
Waiting for the application for Andriod.
