hi all my girlfriend just bough an iphone 3gs 8gb. it seems to be already jailbroken but it doesnt seem to be operating well. bit glitchie. its os 4.3.3 with baseband 5.16.02 on the orange network. i want to restore the factory os and then update it so i can jailbreak with redsnow or something to the latest software and unlock the network so she can use 02. i recently jailbroke my iphone 4 with snowbreeze, but still waiting for 4.10.01 unlock and im not sure if i update the 3gs to 4.3.5 os that the baseband will be unlockable like the iphone 4 did to me... (that was a big opps) any ideas how i restore and do a fresh jailbreak to be able to unlock it right?
