iPhone, iPod touch, iPad
The Home screen is the first thing you see after you slide your finger to unlock your device. You will see quite a few default icons including Contacts, iTunes, App Store, Settings, Photos and more. When you download third-party apps, the icons are placed on the Home screen. The Home screen can only hold a limited number of icons (16 + 4 on the dock for the iPhone/iPod touch; 20 + 6 on the dock for the iPad).
