Just picked up a 750 to play around with (contemplating a switch from Sprint) and I noticed that even after being closed with MagicButton and when disconnected from the PC, ActiveSync starts itself up every 5 minutes. I shut it down, it comes right back.
I searched and found no real solution to this issue. If I use the ancient "fix" from the Axim forums, my push email no longer works since I have to change the option from "As Items Arrive" to "Manually."
Help? Any ideas?
