warning: iPhone/iPod Touch: application executable is missing a required architecture. At least one of the following architecture(s) must be present: armv6 (-19033)
Answer:
For some reason the default architecture settings with xCode 4.2 is only for armv7. Go to Target -> Build Settings -> Architectures -> Release on value dropdown pick "Other...",
remove $(ARCHS_STANDARD_32_BIT), and add 2 rows first with "armv6" and second "armv7"
Done
