Update: See Read More on Dvorak for iPhone for more!
It's here, and it's the real deal: a Dvorak keyboard layout for your iPhone. Unlock your iPhone, run Cydia, and install the Dvorak Keyboard addon for iKeyEx. To activate the Dvorak layout, tap the globe key until you see the familiar AOEUI key sequence. As a bonus, you get punctuation keys like ',.?- on the primary keyboard; you don't have to tap the 123 key for punctuation, as you do on the iPhone's Qwerty keyboard.
