I too had a problem with my Treo getting caught in a never ending Hot Sync loop! After exahusting all options- soft reset, warm reset, re-installing the Palm software, upgrading my palm software, I finally did a hard reset. I temporarily thought I corrected the problem when my phone was in "organiser" mode- but as soon as I activated blue tooth or put the actual "phone" on, it would immediately go into hot sync mode. Even the hard reset which is upposed to fix any software related problem did not help. The device still went into hot sync mode.

After several hard resets, I had my treo replaced. At the verizon store, I was informed that you sould only have to do a hard reset once, and if the phone still doesn't work, it needs to be replaced. Obviously this is a problem instrinsic to this phone model. That explains why it was on "clearance" for $49.99
This problem resembles a "virus" that starts on the palm desktop software and it eventually corrupts the phone to the point of no return. Perhaps it is a defective file- but the end result is the same- the phone must be replaced!
Based on reading this forum, I have noticed that some individuals have had to reolace their phone three or moe times. My only suggestion is this: if you are unfortunate to be stuck with this phone and have it replaced, then you need to uninstall your palm sotware and reinstall it. Individually find the files to back up your address, calandar and memo data- if you can identify & find where they are stored and wipe out everything else. You will need to start from scratch.
