Will Blackberry Curve 8310 SIM card work with the 1st Generation iPhone?

I have a blackberry Curve 8310 on AT&T, and I might get a iphone from someone and I was wondering if that was possible. I know how to unlock the iphone and all and not sure if it works or not. Also, will AT&T know if i switched to iPhone or not?

Yes you can swap once you unlock the iPhone. Be sure to unlock it through network provider or a trusted online unlock vendor. Some free methods claim to unlock and scam the users. I suggest you can approach Wickedunlock.com and specify the country,locked network of iPhone.Based on the availability you can get the permanent unlock service along with free instructions. The network provider has a lot of chances to know that you have swapped networks since the signal will come from a different IMEI number.
