First problem application loader gave a message "duruldotnet/build/Debug-iphones/duruldotnet.app is not a valid location for the app. it must be at the top level of the archive" second problem: iphone/ipod touch: application executable contains unsupported architecture(s): i386 third problem: application failed codesign verification. The signature was invalid, or it was not signed with an Apple submission certificate. fourth problem: unable to extract codesign entitlements from your application. Please make sure DrillApp is a valid Mach executable that's properly codesigned. So for this i must walk through the Development Provisioning Assistant??
