i took the sim card out of my cingular 8525 and replaced it with the one that came in the iphone. Activated my iphone with my old sim card through itunes, had to do the plan upgrade, and it works... let me grab my brothers sim and stick it in and see what happens..

nope, just plugged my brothers sim in and it came up with
Incorrect SIM Please connect to iTunes to reactivate iPhone.
so i guess u do need to add the iPhone plan... but its on ly an extra $20 or soo with unlimited data, and 200 sms.
QUOTE Thanks
