I've been using the iPhone from O2 for just over a week. Got my mobileme account set up fine and for the first few days emails were pinging away as they arrived on the phone. But for the last couple of days they only seem to show up on the phone when I actually open Mail and it connects up. I don't think I changed any settings on the phone or the MacBook and everything still seems set to push the email to the iPhone, but something has definitely changed. I don't see any other mentions here of similar problems at the moment, so user error is a definite possibility. Any idea what I might have done or, if the blame lies elsewhere, how I might resolve it? It's not a killer problem for me, but it's a puzzler. Thanks in advance for any help.
