Can you name some top selling sprint smartphones?

Sprint Smartphones are now one of the basic needs of anyone who is a professional. 3 months back I was in a same kind of a fix while I wanted to buy myself a new sprint Smartphone whether which way to go. But my choice got stuck to HTC Touch HD T8282, Its 3.8-inch display is the biggest in this field and its WVGA (480x800) resolution is amongst the sharpest. The Touch HD feels fantastic to hold. It has an auto-focusing 5-megapixel camera that sadly lacks a flash. A second front-facing camera lives above the large touch screen and is used for video-calling. It has HSDPA technology, Wi-Fi, a built-in GPS receiver. The Touch HD also makes use of the same excellent Opera Mini web browser. And its price is as exciting as it range starts from $437.63. And if it doesn't clears the doubt in your mind than you should have a look at the Samsung Galaxy SL I9003, a LCD touch-screen display Android Smart-Phone, .It is powered by a 1GHz processor and features high speed connectivity 3G and Wireless LAN Wi-Fi and its range definitely fits in your budget with its starting range starting from $400. Also with a starting range of $412 the Sony Ericsson XPERIA X10, could be a good choice. It is the first android phone from Sony Ericsson. Its 8.1-mega pixel camera with autofocus remains its prime attraction. Nokia, Blackberry and LG also serves as some of the best Smartphone producers.
