Add Folders to the Dock

The ability to create folders is one huge improvement brought with iOS4, and is a very popular feature when it comes to organizing and accessing apps. In using folders, there’s a neat trick that will let you have all your most-used apps on your phone’s homescreen.

To create a folder, just press and hold any app until it starts wiggling. Then, drag the app into another app that you’d like to include in the same folder. The iPhone will automatically generate a name for the folder based on its contents. You can edit this name by pressing and holding the folder icon.

Once you’ve got your folders made, if you clear something less useful out of the dock (you can only have four things in at a time) you can drag and drop your folder into the dock for super-fast access.

With clever folder creation (Work, Play, Phone, Tools, etc) you could pretty much have everything you need one tap away from the homescreen, rather than scrolling through endless screens of apps.
