Help exporting to xcode

Recently I downloaded the new pre-release xcode from the apple developer website and now when I export to xcode all of my frameworks are red and do not work. Furthermore I can not run any of my applications made in unity on my iPod or in a simulator.
If anyone could help it would be GREATLY appreciated.

These are the errors that I receive:

error: There is no SDK with the name or path ‘iphoneos4.0’

warning: iPhone apps should include an armv6 architecture (current ARCHS = “armv7”).

Update your xcode…

it potentially is updated, cause with 4.1 sdk it won’t find it either.

ensure to go to project - edit active target and set base sdk to whatever iphone sdk version you have and iOS deployment target to what you want / can support
