Samsung has just officially announced the launch of its i550 cell phone. This handset comes with a build-in GPS receiver, allowing users to track their way home. Other features aren’t kids-toy either. For example, a high-quality 3.2 megapixel camera module with flash and auto focus functions, support for EDGE and UMTS/HSDPA for high-speed internet access, USB 2.0, and wireless Bluetooth 2.0 connectivity.
