Use QuickPwn to get it jailbroken on 2.0.1 firmware if you can, im not sure if you can get it back from 2.0.2 back to 2.0.1. But putting it into DFU/Recovery mode and then pressing **** + restore and selecting the 2.0.1 firmware. After that if it works, use WinPwn and create a custom firmware and restore it to that. Here is a link to the guide for unlocking and activating your 2.0.1 firmware using WinPwn after QuickPwn :
