I have 5.3.1 running on a Powerbook 10.3.9. I have tried in vain to sync my Verizon Treo 650 with NUTD & Contact. I purchased Missing Sync but that did not work either. I've worked with their customer support for the last couple of days but syncing crashes at Contact & UTD (the customer support was great but referred me back to here). I've posted this here previously and tried installing & reinstalling and purchased Missing Sync as a recommendation.

Is there a different Smartphone that would sync with 5.3.1 (newer Treo, Blackberry or something else)? I do have a $300 credit at Verizon for a new phone but am I going to have the same problem?

Thank you!!
