Hi guys,

I've seen too many guides around and I am a bit confused, lots of people doing it in different ways.

I've got an iPhone that has 1.0.2 unlocked for any SIM card (and working), with modem firmware 04.01.13_G, I don't know if it is an original 1.1.1 downgraded or a 1.0.2 simply unlocked.

I would like to know what safe guides do you suggest to perform the 1.0.2 - 1.1.1 - 1.1.2 upgrade/jailbrake/unlock?

Please note my current firmware is 1.0.2 and my modem FW is 04.01.13_G (maybe I will need to revirginize).

Oh, and I would prefer Windows guides (no MAC user yet

Thanks in Advance
