Just bought & upgraded to a W880i about 2 weeks ago; wanna check if anybody has encounter problems as below;

when I leave the phone sitting sideways on the 9.5mm thickness section, it shuts off say after 5 minutes. Other position no problem.

cannot command dedicated MP3 ringtone to individual in phonebook even though profile of the person indicating ringtone has been change but still ringing the general ringtone.

Are these problems normal? I have used W800i & W810i and still having it at the moment which do not give any problem at all for this menus. Any advice from sifu out there?

Not very sure about the firmware, it's got chinese characters & recently bought at Digital Mall. BTW how to check firmware from phone? What's the latest firmware with chinese characters?

Anybody can tell me how to check the firmware from phone controls?
