Hmmm... thats interesting...

So I upgraded and JB'd my 3Gs 4.2.1 with GP_rc6.1 on windows.
Went flawlessly.
After I reinstalled Cydia and then all my JB apps with aptBackup.
Again flawless.
After the reboot from aptBackup, all my spacing on the springboard is oddly different. (see attached picture) I've never had that much space below the bottom ribbon. Anyone else experience this or similar?

Do you have any themes running? any winterboard plugins? have you tried rebooting?

My gut reaction is that this had something to do with a dock modification...did you have something installed to remove reflections, or shadows, or anything like that? If so, try removing it.

I had to disable all visual themes to make the spacing better. Now as I "shop" around for new themes im finding some that do that spacing thing and some don't. Ah well. I liked that theme.

If you liked the theme why not figure out what element messed up the spacing and edit it to take it away?

I could, I guess, but it's pretty low on the priority list for now. I may just stay "stock" visually for now for something different. Themes are nice but not my first reason to JB.
