Maybe it's info you can find online, but I sure didn't find it. Will devs be able to create apps for the iPhone 5 only, or is it mandatory for them to include the older phones? If they don't require it, it'll only be a matter of time (i admit, at least a year) before the axe app support for the 4S and older. Also, if it's possible to only build for the new iPhone 5, how will they support the 2x mode on the iPad? You can't find 1136x2 on the iPad, and I doubt they'll build a 1.78x button.
