I thought I was going crazy because every once in a while my treo would be flashing orange (like when you're out of the coverage area). Well, I finally figured it out yesterday...

I had installed callrec, which will record phonecalls. I was under the impression that it only WORKED during phonecalls, but no, it works all the time.

So callrec is not only a handy call recorder, but a handy voice memo application which is launched at a push of the side button.

Crazyness turns to excitement.
