Ok I was trying to upgrade my 1.0.2 iphone to 1.1.1 abut my wifi doesn't work so I was doing it another way and it didn't work. So I tried downgrading back to 1.0.2 and it worked except when ever I try to put any applications on the phone they don't open they just go the first image of the application and does nothing. Does anybody know how to unlock this phone now it is a 3.9 boot loader? Thanks
