supporting 3.0 on SDK4

[lefty]

If you want to support iPhone OS 3.0 what settings should you have?
Ok. I know base SDK has to be OS4 and deployment target has to be 3.0.
But what about "valid architectures" and compilor version?
To be compatible with 3.0 does it need to be gcc 4.2, or llvm 4.2?
armv5, armv6?

Well I figured out the valid architecture, but the compiler version is still a mystery. I used to use gcc 4.0, but that no longer works in SDK4. So, I choose gcc 4.2 and keep my fingers cross, because there is no way to tell if the build works on OS 3.0 device or not
