Hi,

I've released a new application, BlackBerry Alerts, for sale that may be of some interest. It provides capability for repeating audible alerts for:

Missed Calls
SMS Messages
Voicemail (may not always work perfectly since there is no access to the voicemail flag)
Emails
PIN Messages

The alert can be set to repeat every 1, 3 or 9 minutes. There are a lot of options so it is highly customizable... mostly you will want to check out missed calls, sms and voice mail alerts.
You can set it up to use a profile so can choose any of your existing ring tones.

Version is compatible with the Pearl but there is an issue with the Pearl dialog for Missed Call view/close (thanks to PaulQ from this board for lots of testing). Still working on a Pearly Only version with Paul but license keys will be transferrable between the two.

OTA Link (Demo Only, not available late night)

Let me know any problems/suggestions. Working on future version to include separate notification for each alert type. Free future upgrades provided (keep license key).
