How to solve armv6, armv7 problem in order to distrubute my app?

In order to distribute my app via App store,

Is it nessecary to make my app excutable in both armv6 and armv7?

After I upgraded xcode version to 4, My app don't be compiled.

Because external libraries don't support armv7.

This is error message.

Yes you can submit it that way, but it's not preferable since the compiler will not optimize for newer phones. You should get updated libraries to support armv7 and i386
