Microsoft Windows for SmartPhone 5 is the latest edition of the Microsoft SmartPhone series, which is essentially a customised version of their Pocket PC operating system designed for use in today's latest mobile phones.

This powerful software enables users to run thousands of games, applications and playback nearly every file format available - including MP3,WMA,DVX,MPG formats.  Compatible with all GSM networks in Australia, and very much a favourite of the staff here at National Office Technology, the SmartPhone SP5 is definitely a powerful mobile phone that will outlast most other non-smartphone based mobiles.

With software being written for these and other brands of SmartPhone everyday, and its ability to designate normal WAV files as ringtones, you can change the phones applications, themes and sounds anytime without having to purchase them from operators (though you can do this if you find one you really like!).
