I have a used Apple iPhone 4 16 GB for Verizon. There is no contract connected to it.
It works perfect and I have been the only owner. There are some scratches on the front and some on the back, but absolutely nothing significant.
The iPhone 4 is a follow-up to the popular 3GS design and steps up to a really high-resolution display, 5 megapixel electronic camera with LED flash, and 720p HD video recording. This design also showcases a front dealing with camera, a large multi-touch display, complete web browser, WiFi, Bluetooth compatibility, GPS, and 16 GB of internal memory. The iPhone 4 is a feature-packed smartphone with quad-band GSM and WCDMA modes supporting international use. This phone features 16GB of memory.
