So I didn't actually get it going yet, because I'm probably moving to a new mailbox, but Helio just launched its Microsoft Exchange support... and they pushed the little sucker right to my phone without telling me. I had to find out from another blogger. Apparently, tech is ahead of PR.
Assuming this works, even if its just a timed sync, its awesome.
Now if only that Exchange server could be Gmail/Gcal, I could die.
