I was punching in numbers and figured an iPhone user would save alot of money if he/she bought a no commitment iPhone and switched carriers to virgin mobile. But can that be done? i called Virgin Mobile but i got a fob lady and i dont know if she knew what she was talking about but she said the network wont recognize the device. does it matter if u got a virgin SIM inside ur phone??? i need to know!!! i dont want to fork out 70$ to att every month! Thnx in advance.
