Can anyone tell me if a Blackberry 7150 can have the DTMF tones lenthened. I need this to access a system that can't quite get the dtmf tones the way they are currently set off of our blackberries. Thanks!

7150 doesnt exist yet :D

But No I don't think you can change the tone length.

If you want a really long tone length, get a 7100. It goes on forever and you never know when it will stop. The duration of the key press doesn't seem to matter much either. I had one last about 5 seconds the other day.
