after google i found no help. i currently acquired an i phone 3g running 3.1 with modem firmware 05.11.07. i have heard any 4.xx software doesnt play nice with iphone 3g. so how do i upgrade to 3.1.3? i tunes wants to update it to 4.2 i dont want tht, and im sure it wont preserve my baseband. any help is appreciated. i have the 3.1.3 ipsw downloaded but have no idea how to load it on my phone. also once i figure to load it, the baseband will stay the same. so what if just use green poison to jailbreak, install cydia and use ultrasn0w to unlock. will that work?
