I am looking for some info surrounding the iPad keyboard. WITHOUT jailbreaking the device, I was curious if someone has been been able to manipulate the look of the keyboard. The functionality should remain the same, but the actual look should change. I was curious if anyone could change the color or shape of the keys.
Not without jailbreaking. With a jailbreak, there are several options for doing this though.
The one that comes to mind immediately is Winterboard, which isn't relegated just to keyboards, but theming the entire OS.
There is also Color Keyboard, which changes the look and feel of the iOS keyboard (although it is iPhone only).
