please help, the people over at hackintosh forums were jerks and didnt answer my question so i came here,

is there a way to know if the iphone that i purchase from an at&t store has the 1.1.3 firmware, like for the 1.1.2 you could tell by the week number in the serial number.

also do you think its possible to buy a 1.1.2 firmware iphone still at a local at&t store, i live in the detroit area

thank you in advance for your help
