Firstly I use oAuth on my iPhone app because I like the concept but there are problems with the oAuth pages using mobile devices, so here are my suggestions to make the experience better
1) The page simply doesn't lend itself to a 320px wide screen. How about an auto-device detection similar to that used on the search.twitter.com site? 2) The default button is deny rather than allow... so if you press the keyboard 'DONE' button on the iPhone or hit the enter key on your keyboard it submits the form with DENY rather than ALLOW. This is very frustrating to ask the user to then go re-send their oAuth request because they've just used a keyboard shortcut rather than clicked the Allow button. What's everyone elses thoughts?
