HELP - I've lost all my Calendar data, most of my Notes, and other issues
In priority order:
1. Sometime in the last two days my iPhone 4S, with IOS 7.0.4, lost all my Calendar data except birthdays from Contacts.
2. Most of my Notes are lost except those from PC.
WRT the above, iPad data is still intact.
3. IOS 7.0.4 crashes apps A LOT! Even Apple apps.
4. IOS 7.0.4 is slow.
iPhone 4S, iOS 7.0.4
