Me and my friend both had this problem on our iphones , but a lil different . when ever we searched for wifi nothing showed up but when we restarted the phone for the first 10-30 minutes we were connected then the connection was lost. my friend upgraded to 1.1.1 since he was on at&t and now his iphone works perfectly but mine is unlocked and that wont do it !

! anyone out there with a soloution ? PLEASE !
THNX
