There is nothing like an iphone and I am planning to buy a good iphone and I want some features like support for high-speed 3G networks, third-party applications, and expanded e-mail, improved call quality and an excellent music and video experience. I have done a little research about various iphones in the market and found that iphone 3gs has similar set of features but I do not know about its specs so provide me detailed iphone 3gs reviews.
