Mine was set this morning and didn't. I confirmed everything was set properly. It's gone off daily previously to today. I seem to remember this happening with my Nextel berry sometimes as well. Annoying as ****.

I have pretty good luck with mine, always. I do recall reading like one other post here one time someone commented theirs did not alarm.

I have used MAlarm primarily, much more customizable than the stock alarm, 6 alarm times, more snooze options AND free.

Look in the FAQ, Third Party Applications section.

Mine has always worked. Just be sure after setting everything to "Close" the application. Setting a backup alarm, however, may not be a bad idea.

Strange that their are two posts about this issue today. Hmmm, I have no troubles with mine (Set to daily) .. However, I will make sure that I keep my actual alarm clock set (just in case my BB Fails) .. Would hate to be late for work.

Mine has never failed.

Me either ... But now I have this incredible urge to cross my fingers.
