What are the differences between the iPhone models for AT&T and Verizon Wireless?

Other than the networks they use, both models offer the same innovative features: FaceTime video calling, Retina display, HD video recording, 5-megapixel camera, and more.

iPhone for AT&T uses GSM technology for wireless communication, while the iPhone 4 for Verizon Wireless uses CDMA technology. That means the iPhone model you purchase is configured to work only with the network technology of either AT&T or Verizon Wireless, as specified, but not both. In other words, you cannot use an AT&T GSM phone on Verizon’s CDMA network and vice versa.

Will existing iPhone 4 accessories work with the new iPhone 4 for Verizon Wireless?

All iPhone 4 accessories available from the Apple Online Store are compatible with iPhone 4 models for both AT&T and Verizon Wireless. Accessories that use the Apple dock connector — such as speaker systems and docks, car accessories, and power adapters — and carry the “Made for iPhone” badge are compatible. Because the button placement on the CDMA model for Verizon is slightly different from the GSM model for AT&T, some form-fitting cases, purchased previously or purchased elsewhere, may not fit the CDMA model precisely.

If I lose my iPhone, can I buy a replacement iPhone?

Yes. Visit an Apple Retail Store or your carrier’s store to ask about purchasing a replacement iPhone.

When I buy from the Apple Online Store, does my iPhone come ready to use?

Yes. When your iPhone arrives, all you have to do is connect it to iTunes to activate it with your carrier and sync your contacts, music, and other data. There’s no need to call the carrier or visit a store to complete the activation.
