i am getting a replacement 3G from apple tomorrow. i am a tmobile customer. i understand when you connect your BRAND NEW iphone to itunes, it asks you to activate using the AT&T sim card.
is it possible then to jailbreak and unlock without activating this? clearly, i do not have the AT&T sim to activate this.
can i do this ...
1. once connected to itunes, restore using iPhone1,2_3.0_7A341_Custom_Restore.ipsw ?
2. then afterward unlock using ultrsn0w?
