I have a Treo 650 and it is ok. The phone part is not good. Volume is low, wired headsets don't work with it and bluetooth ones too much wind noise. It works well in my car with built in bluetooth, though it will not upload my contacts.

I travel to Canada a lot and have a Canadian phone, but use my Treo for email, but then have Data roaming.

Is the WiFi in the 8525 going to help reduce my data roaming? Also, is the phone part on either one better than on the 650?
