T-Mobile is the first network in the UK to announce the new Motorloa KRZR - or the K1 as it's also known. Just 4.2cm wide, this slimmed down version of the RAZR offers superior features such as a two megapixel camera and Bluetooth wireless stereo.

At a mere 10.3 x 42 x 1.6cm, the KRZR is a dinky phone, but it's still quite heavy: 102g. A Micro SD card slot is available for memory expansion, as the KRZR has a mere 20MB of memory. The music player supports MP3, AAC, and AAC+ formats and you can also watch MPEG4 and 3GPP video.

The display offers a resolution of 176 x 220 pixels, which is fairly low by today's standards. The radio supports EDGE networks and operates on quad-band GSM 850/900/1800/1900MHz networks.

T-Mobile also announced a champagne coloured version of the Samsung E870, a colour that's exclusive to T-Mobile. The Samsung E870 is a clamshell phone with a 1.3 megapixel camera, 80MB of built in memory, and offers similar functionality to other Samsung handsets currently available.

The KRZR will be available from free to £300 on pay-as-you-go while the E870 will cost anything from free to £200 on pay-as-you-go. Both phones are available now from T-Mobile. ®
