Whats up guys, i have t mobile and i always wanted an iphone by the time i bought one 4.06 bootloader with 1.1.2 was already out so i switched my iphone with my friends 1.1.1
I unlocked with anysim and everything worked perfect until i took out the simcard to save all the numbers on Outlook... after i pluged it back in the iphone could not find tmobile and when i go to carrier in settings it says error
i tried using anysim again and it didnt work it said cannot be unlock or something..

Any suggestions from anyone?
