I got the XPS M1330 pre-configured with the Verizon wireless WWAN card. Unfortunately, I'm a sprint customer with a data account already, so I bought a sprint WWAN mini-card to replace the verizon one. Once I made the switch, I've tried everything to get the computer to recognize the card as a sprint card, but it continues to see it as a verizon card. The odd thing is that both services use the same card model, so what do I have to switch to get the card to be recognized as a sprint card so I can switch my account over and start using it?
