I've had MM for 2 years now and have never had a lag problem until I started using the new iPhone. Some mail does not come into my phone until an hour and a half after someone sent it to me. The same mail gets to my Mac instantly. And, yes, I have push enabled on the phone. The red number badge that shows up on my Mail icon on the phone stays there for almost 5 minutes after I read the email. And the gray badge in my Inbox stays there for hours after I read all my emails. All this, and MM functions just as always on the Mail app on my Mac. No problems there. Is anyone else getting this lousy behavior with MM and their new iPhone 4's?
