The extremly unique and stylish 7900 Prism offers an eyecatching design, with prism like buttons and a sleek interface.  The 7900 is a lot classier than the 7500, with a heavier feel but a thiner body.  Also, unlike the 7500, the case is made of matt-aluminium, which adds to the weight and overall sturdyness of the phone.

The phone offers a standard 2 mega pixel camera, which works well, along with features such as being able to change the picture from landscape to portrait, along with colour changes and other minor effects.

Along with the camera, the 7900 features bluetooth and a 3G device with video call support using the VGA camera on the front of the phone.  The Screen uses a pin-sharp new technology called OLED which offers crisp, clear and bright picture quality.

A 1GB internal storage is included, although there is no support for an additional memory stick of any type, which is a shame.  The battery life on the phone is respectable, but not as strong as some other models.
