iPhone 3.0 Mail Crashing
This is for everyone who is having problems with Mail crashing and going back to the mail screen or app screen.
I was thinkering around, I have about 7 different mail accounts, I was going to delete one of them (since I dont use at all) to see if this did anything.
When I went to Settings and then Mail, Contacts, Calendar I found at the end of my list of email accounts a random or dummy email account. I deleted it and that solved my problem.
My battery is working fine now, since its not spending all the time trying to search for this random email.
Hope this helps.
