I need to take some high-quality screenshots in my application.
I would like to use them as a background in some help screens.
But I do not have an iPhone 4.
How else can I create them?
Set up the simulator as iPhone 4 and run it. The simulator window will be huge (because it will display the same number of pixels as the image of the retina on the screen below the pixel density screen). Then take a screenshot! (use capture or any other screenshot app you want!
Good luck and have fun!
