New phone on O2

[Viberious]

My contract is coming to an end next month and I want to a get phone. I've currently got a trusty Nokia 6230i and was going to move to the Motorola V3i but after speaking to 02 cancellations they told me it was purple in colour, is that true?

So therefore torn between V3i or Samsung V600 unless you can recommend another.

Requirements
Slim
MP3
Bluetooth
Sync with PC
Reasonable battery life
