I have a Treo 300 and when someone sends a SMS Message to me my phone barely makes a sign (a VERY soft click). I found a 2 year old thread on this in another part of the forum. The thread never indicated if the problem was solved. Has it been?

Also, several people in the other thread talked about changing the tone for SMS messages as a solution. Where is the option to set tones for SMS. All I can find is to turn the SMS tone on or off. The only tones I can change are "known caller", "unknown caller" and "roaming". Any help would be appreciated.
Thanks, Maus
P.S. I have NO additional software on my PDA right now.
