Sony Ericsson M600, the second 3G mobile phone to feature Symbian 9.1 OS and UIQ 3.0 interface is now available for T-Mobile customers, being the latest addition to T-Mobile's business handhelds.

Featuring a 'full' QWERTY keyboard (although one key is used for at least two letters or symbols, thus not being quite a full keyboard) and a 2.6 inch 240 x 320 pixel 262k color touchscreen, the M600i is a powerful multitasking device that can easily be used both as a fun phone and as a business phone.

The MS Direct Push E-mail and Blackberry connect capabilities, combined with open access to the Net and support for CoPilot Live satellite navigation allow the user to carry out their business anywhere as well as use the mobile phone for route planning and navigation.

Leaving the business features aside and moving on to the multimedia capabilities of the M600 you will find an MP3 player, Bluetooth with A2DP stereo audio support allowing the use of a wireless headset, a few pre-loaded games and 80MB of internal memory to store a reasonable amount of MP3's or documents in the case of business users.

If the internal memory does not prove to be enough, the M600 comes with a 64MB memory card supported by the built-in Memory Stick Pro Duo card slot.

The design of the handheld should not be ignored either. The M600 is slim and pretty light for a 3G mobile phone, weighing only 112 grams.

Also featuring an e-mail setup wizard that makes synchronizing with Gmail, Yahoo or Aol e-mail accounts, Sony Ericsson M600 is now available on T-Mobile and can be purchased for up to £ 230.
