Disable Erase Data Setting
For those that use the passcode lock function, you may want to consider disabling the "Erase Data" feature under the Passcode Lock section. This will erase all the data on your phone if someone enters in the wrong passcode 10 times.
I know some of you have sensitive info and this might be useful but I read some stories of people pranking their friends by doing it on purpose and erasing your phone. So you may want to consider turning this off on the settings menu to prevent an accidental phone wipe.
