I've purchased as a second phone me the part. My main phone is a iPhone4. What can I say. I miss nothing to the part. The phone has all the necessary functions, phone calls, e-mail, Internet, camera, GPS ..... what more could you want. The GPS works perfectly. The only drawback is the small memory of 4GB, of which just under 2GB are free for Apps. Most data Apps can not push on the SD card you. There you can save only videos and pictures. The camera is useful for a cell phone camera. The battery life is at least 2 days off Wi-Fi, which I find very useful. For the money a great phone, but also with a few limitations (memory). In the money but you can not complain.
