The Treo has become so popular in congress and conventions, that is an usual problem when one rings... the most has the clasic Treo ringotne, so it's funny when one rings and all check their phones... Trying to avoid that problem, I choose a different ringtone.. but maybe all in the congress because one Treo rings whit the same tone and all check their phones :))) The best solutions is buy a program to make our own ringotne or use MiniTones, great program that make a ringtone from your mp3.
