First of all I have an iPhone 4 on 4.1 JB. I received an email today at 10 AM. Each time I tried to open my mail, when it started Downloading, my mail would crash. I kept trying and it would keep crashing. I checked my gmail later and saw that I had an unread message. Every once in a while my mail will show 1 unread on my iPhone. Obviously when I tap mail, it crashes shortly after. There is nothing malicious / odd about this email. It's from someone I know personally and have received mail from before. Any idea why this is happening? Ive deleted it from gmail and my mail STILL crashes.
