Wouldn't it be nice to be able to hand your iOS device to a buddy of yours with the satisfaction of knowing that they oculd use your iOS device, but that you could control what they were allowed into and what they weren't allowed into?
A new jailbreak tweak called GuestMode
by iOS developer Ian Burns aims to give you that satisfaction. This tweak gives your iOS device a new Mac OS X-like guest mode feature that offers guest users limited functionality of your iOS device. Best of all, you get to customize what guests are and aren't allowed to do on your iOS device.
When you have a passcode set, you can add a new "Guest" button to the screen, as shown above. This Guest button will bypass the passcode entirely, but once you're on the home screen, you are bound by the rules of the jailbreak tweak. As soon as the device is locked again, you will have the ability to enter your passcode for full privileges, or you can go back into the limited guest mode again.
One of the major things you can customize is what applications the guest user is able to use. For example, you can enable games, but disable personal applications like Facebook, Twitter, Messages, Phone, and more. Applications that are off-limits for the guest user are grayed out, and applications that they can use remain normal-looking, as shown below:
GuestMode adds a preferences pane to the Settings application where you can configure all of the tweak's various options and settings:
You can easily enable or disable the tweak on demand, choose the way you want the user to be able to enter Guest Mode, enable/disable/configure a guest passcode, enable or disable access to the Camera from the Lock Screen for guest users, enable or disable individual iOS features for guest users, and pick the applications (both stock and downloaded from the App Store/Cydia) that you want the guest user to be able to use.
Being able to customize what the guest user is allowed to get into helps you maintain your own security, while still allowing you to be nice and let them use your phone. Whether you're handing your phone to a stranger that asked to make a phone call, or to your kids that want to play a game, you can be somewhat sure with this tweak that they're not going to go through your iOS device and mess up your device or sift though your personal information.
If you want to give GuestMode a try, it's available in Cydia's BigBoss repository for only 99¢. It does require that you have iOS 7 installed.
