Hi Mike-
I've been using the JX10 recently as I just finished writing a
review for the site. I didn't experience any issue with it disconnecting from the Treo.
Just to understand, you are powering up the JX10 and it's not being recognized by the Treo? Correct?
Let me know what's happening and I'll see if I can duplicate with the JX10/700w.
