1.1.1 unlock help please

[mach1mustang_101]

Ok i bought a iphone back when they first came out so they had the oldest firmware on it. i think that is 1.0.0. then i upgraded to 1.02 then i upgraded 1.1.1 havent done any jailbreaking or unlocking of any sort.my phone was used for about 1 month then i got a new phone and sim so my iphone is just like a ipod touch. says no service but i can still use everything else. i went to jailbreakme.com or whatever and got app snapp and the installer and ssh and was able to get the 3rd party programs. ive been searching and found that i am supposed to use anySIM. i got it and ran it and after copying firmware it goes to commcenter and then gives me this message:
Please restart your iphone
anysim cannont unlock this phone. anysim will now quit.
Please turn off your phone and turn it on again after anysim quits.

what do i do to get it unlocked?

should i just go back down to 1.0.2?
