I started a new project with Xcode 4. I know the thing with armv6 and armv7 and sample projects from the web - perhaps written under Xcode 3 - build without bullying me, when I set architecture to "armv6 armv7" and of course deployment target to 4.2.
But when I start a new project on Xcode 4 and try the same it will not run on my iPod Touch with iOS 4.2.1
Many Thanks,
