airtel tricks not working from 10th december 2011

Hi friends, I found airtel gprs tricks like free browsing and downloading using proxy servers (in mobile and pc and torrent downloading) are not working from 10th december 2011.

For me only one trick using operamini in android mobile is working. If any body knows any working trick in Airtel Please share it here.

1. operamini 6.1 apk for android mobiles with realhost 0.facebook.com still working in mobile and also in PC using operamini 6.1 apk in android Emulator.

2. Using Your freedom client trick working with m.twitter.com

Thanks.
