Good Stackoverflow thread on dimensions for the new iPad retina display (among others). See the Answer, not the question.
Presumably because of the iPad’s retina display causing apps to double in size, Apple raised the limit on over-the-air downloaded apps.
Higher Limit for Over-the-Air Downloads
Great apps come in all sizes. If you happen to offer a larger app, we’ve made it even easier for App Store customers to get your app wherever they are. We’ve raised the Wi-Fi download requirement from 20 MB to 50 MB so customers can download apps up to 50 MB in size over their cellular data network.
This really came in handy recently, when I wanted to see a stack trace in the console, and not from the result of an exception! Thanks to this tip found at Bynomial Code, I was able to accomplish this amazingly easily.
As mentioned in the blog, it requires iOS 4.0+, which, from my perspective, is everyone.
