Take security seriously and interested in how to enable data protection on your iPhone, iPod touch, and iPad? The good news is that if you use a passcode, iOS 4 data protections protects the hardware encryption keys on your device, making email, attachments, and 3rd party apps (if they enable it) much more secure. The bad news is, if you updated your iPhone 3GS, iPod touch 3, or original iPad from iOS 3 to iOS 4, data protection might not have been turned on even with the passcode. Not to worry, we'll walk you through all the possibilities, after the break!
If you haven't got a passcode lock set up on your iPhone, iPod touch, or iPad, that's the place to start.
Bonus Tip: You can set your passcode lock to automatically erase your device after 10 failed attempts. That's great if you ever lose your device but if you have young children who can get ahold of it, you might find yourself restoring your wiped device with frustrating frequency. Security is constantly at war with convenience, make your choice.
With iOS 4 you can switch the passcode from simple 4-digit numeric to full on alphanumeric for seriously stronger protection.
A combination of numbers, letters, and symbols is good, pseudorandom is even better but the difficulty in remembering it probably outweighs any benefit.
Now that your passcode is enabled, check to make sure you have data protection on. (It should be on by default for all iPhone 4, iPod touch 4, and iPad 2 devices, but if you updated your iPhone 3GS, iPod touch 3, or original iPad from iOS 3 to iOS 4 it might not be.)
If it's there, you're good to go. If not, keep reading!
Remember, this is only for iPhone 3GS (2009), iPod touch 3 (2009), and original iPad (2010) if "Data protection enabled" isn't showing up on the Settings screen.
Make sure you backup your device before restoring, then choose restore from backup to get all your data back onto your device. Once it's done, sync and then check the Setting screen again to make sure data protection is now enabled.
