I'm having a problem with my TREO. I recently had to have mine replaced through Assurion, which is a refurb. I went through the process of connecting to my laptop to use it as a modem, as I had with my previous phone but, this one disconnects from thr "HOST" when Press "Activate" for the modem link. The other phone didn't do that. I'm wondering if there is a problem with the software of the phone. Any suggestions? Thanks in advance!
