Sometimes it can be tricky knowing whether to look at a message or ignore it. With Message Tone you can make that decision a whole lot easier by hearing who is sending you an SMS before looking at your mobile. It's a simple piece of software - it allows you to assign a different tone to each of the contacts in your mobile, in much the same way you can with ringtones.
The one great feature that Message Tone offers is the assigning of different alerts to groups, contacts and individual profiles which means you don't have to go through every number in your phone and update them all. Personally, I always have my phone on vibrate and if I get a message I read it. But I can understand that some people might enjoy having even more tones on their mobile.
