The lightest and thinnest smartphone of RIM will be available over the counter of AT&T early this summer.

AT&T says that its branded BlackBerry Curve 8900 smartphone will come with both Wi-Fi and GPS, a fast next generation processor, rich multimedia capabilities and ample memory for applications.

This new smartphone has a stunning design that builds upon the success of the BlackBerry Curve with more features for applications, all in a high-quality handset, said Chris Hill, vice president, AT&T Business Solutions. Add to it free access to the nation's largest Wi-Fi network and the BlackBerry Curve 8900 from AT&T delivers unmatched value and performance for personal and business use.

The full-QWERTY equipped smartphone has a high-resolution display (480x360), packed with multimedia capabilities. It has a 3.2 megapixel camera, up to 16gb of microSD/SDHC memory, equipped with on-bord GPS, supports quad-band EDGE (850/900/1700/ 1800Mhz) and Wi-Fi 802.11 b and g.

Customers who get the unlimited plan will be given a free AT&T Wi-Fi access, AT&T said.

The phone will come in an attractive silver and black finish.
