Motorola Droid 3 :: Recently Slowed Down, Sometimes Very Slow?

For the past several weeks, my D3 (got it the day they came out) has become intermittently slow. Sometimes it takes several seconds to respond to a screen touch - most often when placing a phone call. There have been times that it takes 20 or more seconds (sometimes more than a minute) to change to the phone app. Where the request to make a call used to happen instantaneously, it now never happens in less than several seconds.Yes, other apps show slowness on occasion, but none as slow as the phone app.I don't recall adding a particular app and then noticing the slowness.I've gone through the running programs and killed some - no effect on the slowness.I've rebooted and seen improvement - and not, usually not.I've removed several apps that I was not using - no change.It is a stock phone with stock apps and a few common/popular downloaded apps that mainly deal with weather, flying, and tasks/notes.
