Mobile phones have evolved dramatically over the last few years. No longer are mobile phones something you use to call your friends and receive the occasional text message, relying on tiny green screens and pixelated screen icons for decoration. Today's mobile phones are personal entertainment systems with games, applications, multimedia tools and communication systems all built in.

New mobile phones such as the Apple iPhone range and the HTC Touch range afford you the latest in mobile phone technology with the sort of applications you would have previously only expected to find on a PC or a Mac. The best part of these phones is that you can get them for free with mobile phone deals from networks, or if you don't want to be tied in to a contract you can buy unlocked mobile phones and simply use a ?Pay as you Go? tariff.

Some of the best applications for mobile phones can be found on the HTC range, with addictive games and BBC iPlayer installed as standard. You can also go online via the mobile phone's browser and download new applications, with applications such as the ?audio notes? sound recorder that allows you to automatically record phone calls when you receive them.
