cannot connect to internet.

[Guest rnikhan]

Hi guys. $-5 days ago i updated my dell xcd35 from froyo 2.2 to cm7 rom. After updating i find out that my phone is not connecting to internet although i have working data connection. I've tried almost everything,checked every settings under wireless and network but nothing happened. I put my sim to another mobile to check whether my sim has working data connection or not. On another mobile i am able to connect to internet,but on my dell xcd35 i am unable to connect. Before updating my dell xcd35 i am able to use internet. Whats the problem?

There is "E" sign at notification bar, and when i open any site like www.facebook.com, it is also automatically changing to "m.facebook.com" but after that nothing happened and a message appears "connection timeout".

Please friends help me, its very urgent.
