Just got a SE W800i, simply by debranding my K750i. I now enjoy the walkman, flight mode feature, listening 2 radio without headset, higher volume,ability to customize default folders, all on my k750i.I can't shout .
I also applied patches in order to send installed applications and games via blu2t or infrared , install new drivers for camera, change my menu icons,its fun and also challenging as my phone went blank twice .
