I like the first comment: "looks kinda ugly"... Made me laugh...

On a serious note, I don't see the purpose of running Ubuntu on an iPhone (other that the "cool-factor"). iOS works, it's smooth, easy to use and has lots of "apps" (think iFart)... And the iPhone doesn't have a QWERTY.

I guess if You've got an extra iPhone You could use it as a low-power server...
