My iPhone is finally up online with 3.0GM
I followed this guide
http://www.ihackintosh.com/2009/06/how-to-unlock-iphone-2g-with-os-30-gm-gold/
I used iTune 8.1.1 and I found that the custom 2.2 and 2.2.1 both doesn't restore to my iPhone.
1. I follow the guide to downgrade to firmware 2.0.2
2. Then I use the supplied quickpwn to unlock my phone (I didn't install cydia and installer as I know 3.0 will get rid of it)
3. My phone is up and running like before with my T-mobile prepaid sim card
4. Then I use my other machine with iTune 8.2 to UPGRADE to 3.0GM
I mean UPGRADE!, do not RESTORE
