I just Jailbreak my iphone 3g using the tutorial on iclarified then unlock it using yellowsn0w without any problems. The firmware originally was 2.1 restore it to 2.2 and that updated the baseband to 2.28. thank you very much DevTeam. Your magic yellowsn0w 0.9.8 works 100%
I am currently in Saudi and it is working fine with the local carrier STC. Peace

Quick updated: I am unable to access Youtube, restored it three times and no result. I keep getting the msg Loading... but no success. Also, accessing youtube from safari and trying to play video with no success. tried to activate the phone using the original ATT sim before/after jailbreaking no success. Any one has any ideas. thank you very much..
