Contiinuing on from my YouTube comments, It also works in the *videos too, giving things a more organic, Pre-esque feel(which is no bad thing, IMO).
The slider in the settings, can alter the amount of corner roundness.
I'm not sure what the greyed out
Pre Mode is about in the settings. I guess maybe, that it rounds off the top edges
under the status bar, and makes the status bar permanently black, like how the Pre does.

Damn. A jailbroken iPhone
really can do almost anything!
*Edit: It works in
everything, lol.
The white forum background takes away from the overall effet though.
