My iphone was in: 1.1.4fw

I just did:

- Restored an original 2.02 image using itunes
- Launched Quickpwn-GUI and browsed for original 2.01 image
- Followed onscreen steps (basically how to put the iphone in DFU mode)
- Telephone starts jailbroken and activated but not unlocked
- Updated cydia
- Downloaded Bootneuter for 2.0
- Run bootneuter with your choice of bootloader (I used 3.9) and with neuter and unlock options enabled (I left fakeblank disabled)
- After everything was finished, I enabled/disabled airplane mode and the phone got my cellphone provider signal as usual.

Hope it helps, good luck!
