Your first post did not state that data was working before you jailbroke your iPhone. Since that is the case and you've already restored your iPhone, just re-jailbreak again. If it happens again, after you jailbreak try this first before you restore. Using WiFi, go to "unlockit.co.nz", hit continue, custom APN, and select AT&T as your carrier from the drop down link. Follow the instructions. Then go to network in the settings menu, and make AT&T your carrier for the APN settings.... While you would not have to do this under normal circumstances since you already have AT&T, maybe the APN settings got out of wack when you jailbroke the first time. In which case, adding them back in would help.
