Ok! Wait, now I have a phone icon in the applications? I have to drag an icon to my home screen? It's not on the bottom for every home screen now? I'm so bloody confused!
Go to the Applications screens, find the phone icon. Hit the menu button (Bottom left buttom), click EDIT, now click and hold on the phone icon, and then you can drag it down to the dock.
Hope this helps.
Thank you so much! But I can't figure out why it happened. Did my phone do an update by itself?
My phone will arrange the icons by itself once in a while also, it seems just after application updates. They just seem to "wander to another screen", although I have never had an icon from the dock move off it.
At least if it happens again, you will know what to do.
