If you have an HTC Touch Diamond, HTC has a couple of new hot fixes you may be interested in.
The first is a hotfix to address an audio playback skipping issue.
The second hotfix addresses an issue with the Repeat option on reminders. If you can not uncheck the Repeat Reminders in Sound & Notifications in some circumstance, please download this hotfix to resolve the problem.
Note: Both of these hotfixes will need to be reinstalled if you perform a hard reset on your device later.
