@veee1985 redo the whole process again and hope that u can still restore with an official firmware from apple

@lindahansson87 how did u get all that stuff with no internet connection, U have to have internet connection to get the unlock. run over to a mcdonalds or moxie java buy something use there wifi and then download the unlock. if you dont have cydia yet grab redsn0w from the iphone dev team just search that in google "iphone dev team" and it should be the first link.
