Is the a way that i can sync my 2g (thats is JB/Unlocked 2.2.1) onto the same laptop that i use my 3g (not jb) with out it having to restore? i just want to use my 2g as a iPod now, and is there a way that i can change the No Serivce (carrier sign) into something else, i tried MIM but it didnt work. and where can i get the apple dock icons? im tired of the reg stock icons i need a change.
