I updated my phone from 1.1.x to 2.2 and it failed. after a days sweating i quickpwn-ed it using a mac book and the phone seemed to be working ok again. however i have no carrier or a local network (WIFI). How can i get the iphone working again? i.e. being able to see my carrier and my wifi? Do i need to jailbreak it again? Please help since i need my phone for work. thanks in advance.
