I have a Iphone 2G 1.1.4 OTB. I had jailbroken, activated and unlocked it using iPlus. The tool had downgraded the bootloader from 4.6 to 3.9 Fake Blank.
I am intending to upgrade my firmware to 2.0.x but I am not sure what steps do I need to take.
The best / easiest way that I could make out is to use WinPwn 2.5 in the basic mode.
It would be great if some expert can suggest what options are mandatory / preferred for my setup...
