Alright, so I upgraded my touch to 2.0 the other day and initially all of the apps worked (ex. Safari, Mail, Maps, App Store applications) but for whatever reason, my mail app no longer works and it crashes when loading. The interface loads for a split second, but then I'm suddenly sent back to the home screen. Since this is an unmodified firmware, I don't expect anyone to find an easy solution other than restoring, but I just was wondering if anyone else has encountered this issue. P.S. - Obviously I have tried restarting and another thing, is that I am unable to delete my account through Settings.app nor can I modify it.
