We know some of you out there just feinted over that 323 apps figure. It's true--we are gluttons when it comes to apps. But, we don't really use all of those titles for anything in specific, so here's a way to rid of those apps you might not need until a later time.
Launch iTunes and tether your iOS device to your computer. Allow it to sync normally. Now, locate the icon representing your device on the left side of the iTunes window. Click it once with the mouse to select it.
Sometimes, even the simple solution to restoring working backups in iTunes doesn't work. In that case, the ultimate fix is to perform a restore on your iOS device. The biggest drawback about this is that you'll loose all the saved settings, apps and their data, and you'll potentially be forced to start setting up your iOS device all over again, so use this tip as a last resort in restoring your iOS device to working order again.
If you want to restrict access to your iTunes account on your favorite iOS device, it's easy. Launch the App Store app on your device, tap the Featured tab, scroll to the bottom and locate a button that says, "Apple ID: firstname.lastname@example.org." Tap that button and then tap Sign Out. You'll be logged out of the App Store until you download another app in which case you will have to log in again to complete the download.
If you want to prevent your children from installing or deleting apps, launch the Settings App, then tap General > Restrictions. If restrictions are currently disabled you'll see a button that allows you to enable them tap it to turn them on. Create a four-digit pin code if prompted.
