Okay so I messed up. I did not heed any of the warnings of the iPhone dev-team and still go ahead and updated my iPhone 3g to 2.2. And since I updated my fw and thus my baseband, can I still rejailbreak it using Pwnagetool on the guides here and just uncheck the "activate phone" on General tab using the Expert Mode? Please confirm me this. I've been sitting around all day long with my iBrick searching the whole interweb for solution.

Is it even possible? Already updated baseband, use Pwnagetool, uncheck activate phone, still have the baseband updated BUT there is network service?

Possible?
