I have several issues.
Battery. 200 hours standby, my ... . 2 days at the most. Is this due to GPRS On? Can I disable, without killing my settings, my GPRS like Bluetooth? How?
Volume: With headpeace in, the volume is although I set it on LOUD very soft. People complain. Can this be adjusted further?

I tried to solve above, I even read the manual! Is there anybody who can help me on this or give me some tips.

Regards, Paul
