Apple iPhone 4 How to connect iPhone to TV The iPhone 4 is available on both AT&T and Verizon. The iPhone 4 is one of the only smartphones available that you can trust will get you through the day on a single charge and this may be vitally important to some people while others are fine with carrying a second battery to pop in their Android device. Apple does a great job with industrial design and the iPhone 4 feels great in your hand. The display has amazing clarity with the 3.5 inch 960×640 pixel resolution. If apps are important to you then the iPhone 4 is the best choice for a smart phone. The iPhone 4 is a 3G device with no capability for the faster AT&T or Verizon networks. The display is a bit small at 3.5 inches. You can buy the iPhone 4 for $199 (16GB) or $299 (32GB) from AT&T or Verizon with a two-year contract.
