10. You Can Wipe Your Device After Too Many Failed Password Attempts

Want to protect your data on your phone? You need a password. People can crack passwords, however, so if you want to be extra safe you need to wipe the data from your phone after they fail to enter your password correctly too many times. 10 times, in fact. Jump into Settings -> General -> Passcode Lock to find and option called Erase Data all the way at the bottom. If you enable it, your phone will wipe itself out if someone tries to access it and fails 10 times.

9. Siri Can Handle Your Calls

In addition to her (or now his, if you prefer) new voice, Siri can manage your call log for you. Need to listen to a voicemail? Just ask. Want to call back whoever just rang and you missed? Siri can handle that, too. Just make the request and she (or he) will take care of the rest.

8. You Can Change Your AirDrop Visibility

AirDrop makes it super easy to share files with other iOS 7 users in your vicinity, but perhaps you don't want everyone knowing you're ready and willing. If you want to place restrictions on who can send you files, you can just bring up Control Center and click on the AirDrop section towards the bottom left. You can decide if everyone, no one, or only contacts can see you. That way you'll only get file requests from the people you want—even if that's nobody.

7. Night Mode for Maps Avoids Blinding You While Driving

Sometimes you don't want a bright white screen in your face, like when you're driving somewhere at night. Apple's Maps app automatically adjusts based on the time and provides you with a darker interface so you don't blind yourself while driving. You get this feature whether you like it or not, so there's no need to figure out how to turn it on.

6. The Compass App Includes a Spirit Level

Got a few crooked picture frames? The built-in Compass app now has a secret second page with a spirit level. Just line it up against the wall until you get a balanced zero degrees and then you'll know you're hanging things straight.

5. Messages Provides Time Stamps

Ever need to know when a specific message arrived? You can now find out by checking its timestamp in the Messages app. Just swipe on over from the right side of any conversation and you'll see when each message came in.
