Since Xcode 4.5, we are unable to build for armv6 and thus unable to support devices like iPhone 3G anymore.
Would it be possible to use, say, Xcode 4.3 to generate a properly signed armv6 binary and then use lipo to combine that binary and the Xcode-4.5-generated armv7 binary into a fat one?
How would I go about this? Does anyone know a good tutorial?
Would the resulting fat binary be allowed for submission to the App Store?
It appears that someone else figured out how to do it, see this SO question.
I haven’t tested it yet myself, though.
