Can you use iPhone 3Gs (or newer) with build settings?

Question

My application does not work on slower hardware, but I want to support iOS 4.0, which can run iPhone 3G (and the equivalent of the 2nd generation iPod touch). Is there a way to prevent it from being installed via build settings? (I would prefer not to use it in the code when starting the application.)

I thought VALID_ARCHS build setup could do this by removing arm6 (leaving only arm7), but I was able to install directly in the 2nd gene. iPod touch

Answer 1

(I found the answer when I asked this question, but the question "Iphone 3Gs And Iphone 3" is not very searchable, so I posted it and answered it to help others in the future.)

iPhone 1, iPhone 3G - armv6. iPhone 3Gs, iPhone 4 - armv7. (iPad - armv7.)

You must set the UIRequiredDeviceCapabilities parameter in Info.plist to the required architecture (in this case armv7). You should also remove armv6 from the target build settings to reduce compilation time.)
