Mobility Today has a story on “PVR” software for your phone. Softtrends LivePVR software lets your record and rewind/fast-forward thru a buffer of voice calls that you make. Similar to a Tivo it records all the time in the background. I’m going to try it out and will post a review of what I think of the application soon.

Update – I tried this out for a while and it really sucked.  It’s a smartphone app which I missed out on when I first read about it :-)  Doesn’t work so well on my Pocket PC phone.
