Just ordered my 4s, I am coming from blackberry. This may be a dumb question, but- can you have more than one exchange account at a time? I have several email accounts and I understand that to have push, the accounts need to me setup for exchange and not gmail.
Of course, you've been able to do this since iOS 4. It's not new. I've had 3 Exchange accounts and one IMAP account for a very long time. Works great, and Exchange is pushed right to your phone.
@trentandrews - you can set up Gmail as Exchange. You didn't need to switch.
