O2’a latest Xda smartphone has arrived in the form of the Xda sp. Sporting a look that’s pretty different from the usual Xda PDAs (ie, it’s got a number pad), the sp is still aimed at professional types – just ones with smaller pockets. Powered by Microsoft’s Windows Mobile 2003, it’s got all the usual Personal Information Management (PIM) features you’d expect, and there’s 64MB of ROM and 32MB of SDRAM to tide you over on memory. If you need more, you can always bump it up via the miniSD slot, saving images and MP3s to your heart’s content. The 2.2-inch screen is just the usual 65K colour TFT and the camera is the standard VGA as well, making this a pretty average phone, with above average software on board. The O2 Xda sp costs from free on business tariffs and is available now in O2 stores or online.
