"The phone provides a wide array of musical and traditional ring tones, and
it provides 32 slots for user-defined ring tones, which are entered from the
keypad in a manner very similar to Ericsson. I used the tone editor to
create my own high-volume beep alerts for incoming SMS and for my Datebook
alarms. With only a small amount of mental conversion, you could easily
enter a ringtone designed for an Ericsson phone. There are plenty of them
out there. Unfortunately, the ringer isn't quite as loud as it should be,
and noticeably softer than the P280. The ringer is medium-loud, but it could
be much louder."
