Hi all, please help. Became the owner of iphone 3g (American, 3.1.3(7E18), Modem 05.12.01 ) — want to update your device to the latest firmware ( in iTunes Flaunts 4.2.1 ). Understand that updating via iTunes will get a brick... please describe in a nutshell the algorithm firmware/activatie/unlock. What firmware is now relevant in the case of loctim modem? Does it need patching? Chew please. Please clear guidance on which to rely.
p.s. I apologize for such questions. But to go nowhere else.
