So the other day, I got myself HP iPaq 6315. In the past, I had a Motorola Mpx200 and it was great, but to have a my e-mail, calendar info and other things at my fingertips. I also really liked how it provided me with the ability to sync with my mail at anytime.
Because I used it more as pda than a phone, my only complaint was that the functionality and input methods were a little limiting. This was the main factor behind me switching to a Pocket PC phone edition pda.
After I got this ipaq, I immediately noticed that the ring intervals were really long and quiet. After doing some research, I managed to find out how to change this.
There is a registry key which can be used to script how the ringing is. The key on the pocket pc is HKEY_CURRENT_USER\ControlPanel\Sounds\RingTone0
I had it set to increasing ring, but since there was a fairly long gap (about 3 seconds) between rings, I wouldn't really hear it ring. I edited the script string so that it would have a much shorter gap in between and now I'm happy!
Here's a table of various ring scripts pulled from MSDN.
