"the i300 is a candy-bar device and what makes it so unique is the fact that it has a 3 GB hard disk drive to store all type of files and applications as well a mechanical navigation wheel. In addition, for sure, it has the built-in memory as well as a microSD (previously known as TransFlash) memory card slot. Also it features a 1.3 megapixel camera with photo light, Bluetooth (but no W-LAN), a navigation-pad which also can be used as scroll wheel, a 65K color - QVGA (240x320 pixel) screen and is a tri-band GSM/GPRS (GSM 900/1800/1900 MHz) phone but misses support for GSM 850 MHz as well as UMTS WCDMA support.
Unlike announced before - for instance on Microsoft's Windows Mobile 5.0 launch event - the current SGH-i300 devices which will make it to the market soon doesn't features Windows Mobile 5.0 but the older Windows Mobile 2003 Second Edition version only!"
