so i was looking at the screen shots of the at&t gs3 and it holds 4 apps and the applications icon on the bottom of the screen. the gs2 only holds 3 apps and the applications icon on the bottom of the screen. why is that?
Screen size. Bigger the screen, the more real estate for icons there will be. If you want more icons on the dock and/or the home screens, I can suggest using a third party launcher like Nova Launcher for example.
