Same problem here today when submit my app (update) to appstore.

"iPhone/iPod Touch : application executable contains unsupported architecture(s): armv7s"

to remove armv7s is simple, but my app is Universal, will the armv7s-removed app run on all iOS devices (iPhone 5 for example)? when should i build with aremv7s?
