The Apple iPhone is generally locked to the phone company selling them. You cannot swap SIM cards.

NO. It's just like jail breaking an iPod. Simple and easy if you know how to do it and have access to a computer.
iPhone 3G and 3GS, sim card slot is on the top of the device next to the lock button. iPhone 4, side of the device. NOTE: 3G/S and i4 use two different SIM cards. NOT interchangable.
no
A standard sim, so no microsim like with the iphone 4. Just see if your device is not carrier locked, in that case you need a simcard from that specific carrier
