no email information after subject line
When I receive an e-mail, I get the subject but not the message, attachments or photos. I used to get this and did not change any settings.
iPhone 4S, iOS 5.1.1
Try force closing the Mail app: double-tap the home button, locate Mail in the list at the bottom, tap and hold it until it wiggles, tap ➖ to close it, finish by tapping the home button. Now try Mail again to see it's working.
