I used up all the space on my 11 home screens with apps, then installed another app (which can only be found through search as it's installed 'offscreen'). To make more space, I put a lot of different apps into folders.
How do I restore the hidden app back to a home screen?
If I reset the home screens then my folders are lost and an app will be off screen again, and I'd be back to square one.
Running iPhone 4, iOS 4.3.
