iPhone/iPod White Apps FieldTest, iOS Diagnostics, AdSheet on Jailbroken Device : Remove Solution

White Apps Problem

I got this strange problem on my jailbroken iPhone 3G (iOS 4.2.1) after updating my apps from the app store. Some white apps/icons appeared automatically. The apps were FieldTest, iOS Diagnostics and AdSheet. You cannot delete these apps by the default method. The problem is due to libhide a thing that lets you hide icons.

There are two ways to solve this problem:

1. By doing a Hard Reset. To do a hard reset press the Sleep/Wake and Home button for sometime until the Apple logo appears on the screen.
   (Note: This method solves 80% of the iPhone Problems!)
   
   
2. Update libhide via. Cydia and then open SBSettings and click "More", "Mobile Substrate Addons" make sure libhide is toggled on. After this hard reset your iPhone for the changes to take place.

This will help you to get rid of those unknown white apps from your device. Enjoy!
