Do you have a launcher installed? I know Go launcher lets you do that.
Nope. Just using stock... seems to be ok for me so far. I can't stop messing around with my apps and widgets. It's a bit addictive! LOL!
OK, so last night, I finally figured out where I saw what I mentioned in the OP. I had added an app called Car Dock that lets you customize six buttons to show up on the screen (Six HUGE buttons, I might add) when you put the phone in the car dock. There's a setting under preferences in THAT app that lets you specify a "Starting Page" and you can select from among five screens - I guess each of those will hold six apps/widgets/shortcuts as well. Cool.
Anyway, I think that's what I saw and thought I could apply to the main home screen. No dice. So, I just went ahead and reconfigured my screens (I took pics of the home screens with my old BB and used that for reference!).
Could a mod mark this thread solved, maybe? Thanks.
