IPad mail crashes

Question

I just updated my iPad 3 to iOS 6.3.1 and my mail crashes every time I try to open it. I messed with the accounts and found that GMAIL is the cause. I have tried powering it on and off, a hard reset, resetting the network settings, deleting the gmail account and then adding it back and nothing has fixed the problem. To make things even worse the iPad can no longer access WiFi as it now says the password is incorrect. iOS 6.3.1 *****. I would advise people not to update. The last thing I will be trying before going to apple is a fresh restore. If anyone has any suggestions please let me know.

Try this first - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.)
Or this - Delete the account in Mail and then set it up again. Settings->Mail, Contacts, Calendars -> Accounts   Tap on the Account, then on the red button that says Remove Account.
