First of all download an opera mini or ucweb handler.
Then, change your opera or ucweb settings to:
proxy type: HTTP
proxy server: wap.mauj.com or 0.facebook.com or wap.hungama.com
Now change phone Gprs settings to:
apn: rcomnet
ip: 80.239.242.253
port: 8080
now save it....
this works very well on 3G and 2G. But downloading not possible. Because it gives only 30b downloading
