Welcome to iPhone 101, the best place for those of you who are new to the iPhone to learn the basics.
We all worry about misplacing our precious phones or, worse yet, having them stolen. Some may even worry about snoopers trying to read our private info when we're not looking. In case one of these things happen, you should really consider protecting all of your personal data on the device. TiPb has got you covered, to see how to passcode lock your iPhone read on after the break!
From the homescreen, tap the Settings icon. From there you will want to press the General tab.
Once you are within the general settings tab you will see Passcode Lock is set to off.
Now tap Passcode Lock and you will be prompted to enter a four digit passcode.
After entering your four digit code you will now see the following options.
Require Passcode: allows you to select a time period that has to pass before the lock is enabled. If you don't want to have to enter your code too frequently but still want some protection, you can set this to 15 minutes or even 1 hour or more.
Show SMS Preview: on by default, this shows incoming text messages on your homescreen. Turning this feature to off will only display "New Text Message" on the home screen, which can keep the identity of your texter safe from snooping eyes if that's a concern.
Erase Data: simply erases all data on your iPhone after 10 failed passcode attempts. This is the nuclear option, but if you're really worried about losing your iPhone and have really important data on it, it can be something to consider.
Once you have configured your settings as you see fit, tap your home button to exit and that's all there is to it. You have successfully passcode locked your iPhone. It's as simple as that.
