Jailbroke my iphone, and everything was working fine for awhile. Now my wifi doesn't appear to be working. My internet is working on my home wireless, as confirmed by the laptop I'm typing on. I reset the network settings on my iPhone, nothing worked.
Also tried it at Starbucks on the ATTwifi, but it didn't seem to go to a portal page or anything, so I turned the wifi back off and used 3g (which doesn't have any problems). So do I have to restore and rejailbreak this iphone to get this working, or what am I missing???? If I do have to restore and rejailbreak, is there a way to backup my iphone and just restore it once it's rejailbroken to make the process go faster?? I'd prefer not to have to do this, so please light it up with any ideas.
