Free iPhone Keynote and PowerPoint templates help get you from thought to finish
Mockapp.com has created both Keynote and PowerPoint templates of iPhone UI elements, and has made them available as free downloads. Say you had a dream in the middle of the night about the most awesome iPhone app that, to your surprise, no one has thought of yet. Instead of waking up in a deep sweat and scribbling said ideas on paper, you could dream them up on Keynote.
After mapping out your concept on Keynote, you could then pitch it to others in a Keynote presentation. The Keynote and PowerPoint templates include alerts, the iPhone keyboard, arrow icons, buttons, as well as a host of other UI elements.
