Treo slowdowns, restarts and firmware updates

Over the past few days I've been experiencing system slowdowns on my Treo650 - so much so that yesterday alone I had to do a soft reset 3 times. That's the pitfall of being an early adopter and experimenter, I guess. PalmOne is typically slow in issuing official updates - there have been 3 "unofficial" updates so far, 1.15, 1.21 and 1.23. I am currently running (beta) firmware version 1.23. If the official update should come out, you should be able to find it at the palmOne Software updates page.
