Review: iPhone 3G
The menu system for the iPhone has experienced a few changes since the phones release a year ago. You have the basic on-board applications available on the phone's home screen. Out of the box, they are placed identically.
You can, however, move them around to wherever you want. The iPhone now has tons of home screens, that you can access by swiping the home screen sideways. This means you have plenty of place to store all those apps you download from the Apps Store, or other things, such as bookmarks to your favorite web sites.
