To take advatage of the new Inneractive Ad initiavtaive I compiled my App with the latest build but I get the error below: Previous builds complied fine but without the Inneractive Ad code. Any ideas?

warning: iPhone/iPod Touch: application executable is missing a required architecture. At least one of the following architecture(s) must be present: armv6 (-19033)
warning: Icon specified in the Info.plist not found under the top level app wrapper: Icon@2x.png (-19007)

You may have overridden the minimumOSVersion in your build.settings. You should remove it or set it to 4.3 or higher.

I tried that but it made no difference.

I have Xcode 4.1 on my machine should it be upgraded? Do really need Xcode on your machine other than for the use of the Simulator?

you need the version of Xcode that supports ios5 to build for new devices
