XCode 4.2 and ipod 2nd generation

Question

I'm trying to run my application on my old 2nd generation iPod Touch running iOS 4.2.1 to test it on a non-retina device.

It seems that I have all the certificates and provisioning profiles setup properly, everything works with my iPod Touch 4th generation running iOS 5.0.

However, it neither shows my app on the iPod's screen nor the iPod's installed applications list in Xcode. Without any explicit warning from Xcode.

Could you tell me if I should downgrade to Xcode 3 in order to run and test my application on the old device, or am I doing something wrong? Where should I check?

Thanks!

@borrrden is correct that such a device is fine (just tested on one myself, in fact, using Xcode 4.3.x).

My first guess (though it seems odd you wouldn't get an error) is that you are only building for armv7, which at some point became the default in Xcode (don't recall whether this was in 4.2 or 4.3). You need to make sure that your "valid architectures" and related build settings include both armv6 and armv7 if you are targeting that range of hardware.
