This has happened to me twice in 2 days. I pwn my phone and I can connect to the internet over 3g no problem. I install some app updates plus some cydia apps. I go out of wifi range and can make phone calls and send and receive texts but I can't connect to the internet over 3g or edge with full bars one both! I've found a workaround which is to restore the firmware but hell will freeze over before I settle on restoring my phone twice everyday. Has anybody else had this problem? Have you found a solution? I'm gonna try and figure it out myself.. I'm thinking a cydia app is causing the trouble. I'll post an update as soon as I figure anything out.
