This is what you gain by flashing your phone to a W660:

* Walkman 2 (You can skin it!)
* Flash Support (Standby, Screensaver and Menu)
* TrackID
* Updated Java version
* Patches
* If your phone is branded, this will debrand it.

Walkman 2 is a player, just like the one in the K610. It's just that... well, I don't really know what to say about it. You can skin the player and... well, that's the benefit I think.

Flash support means that you can use flash files on your phone. You could use flash menus. The regular themes on your phones are boring while the flash menus are animated and stuff like that. It's much better!

TrackID - It records parts of a song, then it goes onto the net and match it, it's as simple as that.

You also get an updated java-version.

You can also patch the phone. Remove the operator logo, make the phone run without a SIM, edit the font, change the icons of your phone, and so much more!

I hope this helps... and if there's anything you need help with, feel free to send me a PM!
