One that that's always annoyed me with Windows Mobile and how it treats sms tones is the fact that if you have a relatively long SMS tone, it plays its all the way to the end even though you've probably already read and replied to the txt message. Nokia phones have done it forever, whereas you can have a long tone in case you don't hear the short quick "message alert" tones. But, without changing tones, you could also have a quick SMS conversation because when you hit View, it would cut the noise off.
What I really don't get though, is the fact that the alarm acts this way, so how hard would it be to adapt the code for SMS notifications? Perhaps have it hidden when its received, and when you hit the left soft key "View SMS", it pops the little window up with the message, and if it's longer than the bubble, View SMS would turn into View All.
Any other suggestions?
