not sure exactly what your trying to do but i noticed that if i swap a sim on the fly without a shutdown then the sim works fine but after shuting down and starting back up it asks to reactivate thought iTunes and needs takes like 2 seconds.. but its weird that i don't have to until i shut off the phone.
No, no. The swap trick is take 2 iPhones. One activated/one not. If you put the activated sim in the other nonactivated, the nonactivated becomes activated. Remove the sim and you have a touch-ipod. Will an iTunes update v1.3+ on the touch-ipod ruin it?
