I just got the iPhone 4! The iPhone has a 5.0 megapixel camera. The screen resolution is 960 by 640. Apple calls it “retina” display. I love my iPhone, I have not had any problems with it and I think that it is the best phone in the world! Suprisingly, the iPhone 4 has a front camera. And you can call from a video which Apple calls “Facetime”. I have not had any problems with my iPhone yet which is great! I think Apple has done a great job designing and building this phone. It can also record video which is a great advantage. The sound quality is ok, I’ve heard better for whats its all got, its a good sound quality. Personally, the iPhone 4 is good for business because it can hold and mute calls, allow you to talk to more than one person at the same time you are talking to another, and has apps from the App Store that are used for business related things.
