I have had my Treo 650 for about 2 months now and this is my first experience with PalmOS. I've signed up for Sprint Business Connection for email and I'm wondering what options are available that my be a better solution. I run my own Exchanger server and my requirement is that my 650's email is in sync with Exchange and that I have a push email solution. BC handles this satisfactorily, but are there other options available that don't require a monthly subscription fee? Or anything that my be superior to Sprint BC?
