I am getting an iphone delivered tomorrow from the USA. I want to know how do i find out what firmware is on the phone? As now the 1.1.1 firmware is out i will not be able to follow the unlocking guide until i find out the firmware. Then lets say it is not 1.0.2 and 1.0.1 how do i get to 1.0.2 for unlocking the phone. Any help would be brilliant.
