Whether you have the iPhone, iPhone 3G, iPhone 3GS, or iPhone 4, you know that the manual it came with didn't explain everything you needed to know. There are a lot of secrets about the iPhone that its everyday users don't know about, here are a few.

Organize your apps by creating folders. Hold your finger on one app icon until all the icons start shaking. Drag an icon onto another icon and they will be placed in a folder together.

Then tap "copy" on the same menu. Go to wherever you want to paste the text, hold your finger down until the menu comes up, and hit "paste."
