The Dock *memory varies*
The dock is a selection of apps that are available to you know matter what home screen you are on. In the settings you can adjust the number of docks up to 3. With three docks you can swipe left and right on the dock to see the other docks.
To change the dock hold your finger on an icon and a menu will popup:
Change shortcut
Change icon
Swipe gesture action
Dock Settings
Number of docks- this allows you to change the number of docks from 1 to 3 with 3 using more memory than 2 and 2 using more memory than 1. If you have 3 then the middle dock (2) is the default dock that your phone will be on when you turn the phone on.
Enable loop scrolling- with this checked it allows you to go from dock 1 to dock 3 without going through 2 by swiping to the left instead of the right.
Dock notifications- This allows you to have a number displayed next to your messages, gmail, and phone for unread messages, gmails, and missed calls. The number will only go away by tapping the app; using the notification bar to get to the app will not change the notification count. Also this can create lag when going to the home screen because the apps have to check for notifications. *
