    Hi Guys,

    Last night I've updated my iPhone 4 (baseband 1.59.00) from fw version 4.1 to 4.3.3(8j2). I used the latest Pwnage tool to jailbreak it and then installed Ultrasn0w 1.2.3.
    The phone is working fine to make and receive both calls and messages. However, I can't connect to the Internet via 3G or Edge... even though the 3G/Edge sign shows up on the top of the screen.

    Anyone else is facing similar challenge? Any tips to overcome this situation?

    If entering APN's don't work either it might be a jb that didn't go all the way correctly. Restore and rejb if possible and see if the problem persists.
