I've got push mail working great via the MS Exchange hookup to my Google apps email domain. Except that everyone else in my office does that too! I can't find a way to change the sound, so everyone, without exception reaches for their iphone the moment my (or anyone else's) email lands. It's simultaneously + everytime it happens. So someone please tell me if they've figured this one out. Fascinating forum you have here, and this is the first time I'm posting.
