I have a recurrent problem. When I tap on the Mail icon, it acts like Gmail isn't configured yet. When I check in settings, there it is of course showing it's all configured, but no matter-tapping on Mail yields nothing but the "Welcome to Mail" screen that shows all the various mail accounts that can be configured when you're first starting to add e-mail accounts. I end up just deleting the Gmail account and adding it back. If this only happened once, I would be fine, but it doesn't. It's a recurrent problem every 2-3 weeks and thereforee deleting and starting new is not an acceptable solution. I have Hotmail and two yahoo accounts and I never have this problem with them-only Gmail. I don't have any of them set up for push status.
