I recently bought an iphone 3g from a friend, without a sim card. I'm really reluctant to pay for the AT&T service, and I already know about unlocking it.

I've also heard that the Net10 Prepaid company runs partly off of AT&T, and was wondering if I bought a new Net10 phone, removed the sim card and put it in my iphone and then activated it with the iphone's IMEI number, would it work on the iphone?

If not, would I have to unlock it, or would it not work at all?


Thanks
