so my wifi doesn't work. I updated to 3.0 and i think it worked fine, but after awhile my wifi no longer worked (or at would work for a little while and then would lose its connection.) Or sometimes it would 'forget' the password for my router. Has anyone found a solution to this problem? I have done the 'reset network settings' many, many, many times. I have also done a full restore and set it up as a new iphone, it didn't help. i did jailbreak my iphone with redsn0w and then unlocked it with ultrasn0w. I'm not sure if my trouble started then or not, so I was wondering if it might be the baseband.
