What to do, to jailbreak/unlock from unlocked 2.0.2 to 2.2.0

[mainstang]

I have a iphone 2g that I unlocked jailbroke using winpwn 2.5 beta, I used the iclarified instructions. I use itunes 7.6. Currently I have a custom firmware of 2.0.2 running on it. I have heard of to ways to upgrade. Both have you revirginizing to 2.2 software. Then one has you do a winpwn. The other you just Shift click to restore from a custom firmware downloaded from this site.

My main consern is that I can still use an att sim card without having to activate with att. Because that is what I am doing now.

Thanks.

Also do you think 2.2 firware is safe ie. not buggy.

^Yeah, currently 2.2 is probably the best firmware. So what you can do is restore in iTunes and then use Quickpwn to jailbreak and unlock your new 2.2 firmware.
