Several users have reported an issue in which accessing Gmail accounts causes the iPhones Mail application to crash consistently. Likewise, any other applications that access Gmail, including Contacts, crashes when Gmail data are present. Apple Discussions poster rowanpettett writes:
"I did a fresh restore, and synchronized mail, calendar and contacts to our Exchange Server with no problems whatsoever. But as soon as I added my Google Apps IMAP account, my Contacts started to crash if I scrolled to the bottom of the list or tried to search."
There are three potential fixes for this issue:
- Reset network settings: Settings > General > Reset network settings
- Restore the iPhone in ITunes.
- Change password Navigate to your Gmail account page on a computer and change the accounts password. Next, delete the Gmail account from the iPhone and reestablish it.
