The AT&T version of both the iPhone 3GS and iPhone 4 are built on what's called GSM radio technology (used by both AT&T and T-Mobile in the US). Meanwhile, Verizon and Sprint use a completely different technology called CDMA. The two standards are incompatible. They use different radios and operate on different wireless frequencies. So, no, you cannot take your existing AT&T iPhone and walk into a Verizon store and simply switch networks. Even if you own an iPhone 4 you will have to purchase a completely new iPhone 4 with CDMA chips in order for it to work on Verizon.

Yes. Both the iPhone 4 and iPhone 4S work on Verizon's network. However, you will need to buy the version of the 4 or 4S that is compatible with Verizon.
