hi there, picked up a locked iphone 4, to UK orange (now EE). i am trying to jailbreak the firmware.. as when i picked it up the previous owner already whipped all the data on, and was stuck at iphone activation screen, now. I used sn0wbreeze and i downloaded the iphone 4 [GSM] release for the iphone, however once I placed upon my iphone, the phone is now STUCK at the Apple Logo, and will not go past.. how can I do this? Have I downloaded the correct software? thanks.
