Windows Mobile smartphones are appearing in ever greater numbers in the UK, but there are few operator-free choices. However, Dubai-based i-mate has recently announced a pair of options -- the SP5 and SP5m. The duo are very similar in specifications and have two key selling points: they run Windows Mobile 5 and have built in Wi-Fi. The 'm' model has dedicated buttons for controlling music and is therefore more of a consumer offering, so we are concentrating here on the basic model.
