Maybe it's somehow a springboard backup method? Seems too coincidental to me that a Springboard Cydia tweak is also called Backboard.... Hmmmm
I found that earlier, yeah.
I have my doubts that this is another 'wifi sync' to 'wifi sync' jb to gm type thing, though.
Springboard seems to be the LAST thing Apple and Ive want to complicate, so in the back of my mind I imagine some sort of secondary home screen with a multitude of info.....
I use a jb tweak that puts a list of running applications under my spotlight search bar. That space is SEVERELY underused, I'd love to see a widget page back there... maybe in my dreams.
