Jailbreak had nothing to do with unlock, you need to unlock it with blacksn0w

Jailbreak had nothing to do with unlock, you need to unlock it with blackra1n

i've done that and iTunes keeps saying that only compatible SIM cards from a supported Carrier may be used to activate iPhone. Any other suggestions ??

I think you may have to use blacksnow for the jailbreak

If you are using windows pc, open up itune, hold down the shift key and click restore, browse to the ispw file and restore.

Or you can jailbreak again with blackra1n, I believe it will hactivate you iphone, and than use blacksn0w to unlock.

No, no, no. You're getting bad advice here. The problem is not your jailbreak, it is the way you're trying to unlock. You have a 2G iPhone. You can't use blacksn0w to unlock. You need to use BootNeuter to unlock your phone. You can install it from Cydia.

I had the same problem, I have a friend that is on AT&T so I borrowed his SIM card just long enough. Once it recognized the SIM card, I was able to switch back to my T-Mobile card and all was good to go. Try it, no harm. Good luck...
