Nothing pushes to my first gen iphone running 2.0. I have yahoo, mobileme, and mail2web exchange all set up. All are configured and are set to push. Email comes through, but only when I check it manually, but opening mail.app. What's the story with this? Is anyone else getting push mobileme, yahoo, or mail2web? Do I have a bum device? I activated using pwnage, if that matters, but I'm using an at&t sim card with a blackberry data plan.
