After installed ultrasn0w, you can use different network carriers.

AT&T SIM card is use for activation via iTunes.

For 3G user, you can upgrade 4.0 via iTune 9.2, jailbreak with redsn0w and unlock with ultrasn0w.

For upgrade iOS 4.0, it is possible on 3.1.3 (Spirit, old bootrom). I did it on my iPhone.
