Does anyone know of an app to allow wireless sync of my Orange treo 650? I used to have an app on my nokia 6630 called MightyPhone, which synced to a web based service. A companion app ran on my PC and synced with the web based service. What was clever is that when a change was detected on outlook, it was synced with the web service. That triggered a special SMS to be send, that, when received on the phone, caused the phone to sync with the Mightyphone service.

Mightyphone doesn't appear to support palm based devices, only Sync-ML based devices such as Nokia, Ericsson and some others.
