my friend has a 1.1.2 iphone.
wanted to give it to me so i can put a turboSim and make it work..
the only problem is that for some reason he accidentally updated to 1.1.3.
I downgraded to 1.1.1 then jailbroke the phone then okToPrep and back to 1.1.2
now is thee a way to get the modem Firmware from 04.03.13_G back to 04.03.13_G ?
