Just got a Droid Pro, my first droid, seems great. Tried to set it up to get my Exchange email, but it looks like the more frequent email frequency setting I can pick is 15 minutes. So that means I'll only be alerted of new emails every 15 minutes, which seems like quite a long time if you're a frequent emailer like I am.
Is that really the closest to real-time I can get, every 15 minutes? or is there an upgrade or something I can do to my phone to make it more frequent?
