Sony Ericsson’s announced availability of two previously unveiled music-oriented handsets and the broader availability of an erstwhile Vodafone exclusive. The W910 and K850 were both announced back in June, while the K630 is essentially a rebadged Vodafone V640i.

The W910 has a cool shake operation option, allowing you to skip or shuffle through tracks stored on its 1GB Memory Stick Micro card with a flick of the wrist. Its 240 x 320, 262,144-colour screen should also be good for displaying pictures captured by its two-megapixel camera.

It’s also set-up for quad-band GSM/GPRS/Edge and has 3G HSDPA connectivity. However, Bluetooth will also let you hook it up to headsets and stereo headphones.

If you’re looking for more megapixels, the K850 has five of them. It’s also got a xenon flash, auto-focus system and 16x digital zoom, although its display is no better than the W910’s. It also has 3G connectivity with HSDPA, much like the W910.

Sony Ericsson's K630

Finally, don’t be fooled by the ‘new’ K630 because its looks and features are identical to the limited-edition Vodafone V640i. For example, both handsets provide HSDPA 3G and tri-band GSM/GPRS/Edge connectivity, with a video talk time of up to 2.6 hours. Both also have Bluetooth 2.0 with A2DP for wireless music streaming.

The K630 matches the V640i with its 2in, 176 x 220, 262,144-color display and ships with the same size 32MB internal memory and 256 Memory Stick Micro memory card, although both handle up to 4GB cards. But if you’re still not convinced it’s essentially the same phone, then it comes in Havana Gold, just like the V640i does.

All three handsets will be available later this month, although Sony Ericsson hasn’t yet confirmed prices.
