Just a quick warning... I have an unlocked iPhone 3G and an AT&T locked iPhone 3G. After the update on my locked iPhone 3G (using sim proxy), it does NOT work anymore. It only says SIM FAILURE. Please be aware of this POSSIBILITY. It may not happen on all sim proxies, I will test more, but as for now, a perfectly working iPhone 3G is USELESS... Just an FYI!
It will happen on all SIM proxies.
That's what I thought! Thanks Zf_ !!

Took awhile just to activate my official unlocked iphone on 2.2.
It says phone is unlocked :).
