When I try to build my app, I get only two choices for the target OS -- 2.2.1 and 3.0.
I reverted to the latest 3.1.2 build of the iPhone dev kit.
But I can't install the code on my test device because it's at the 3.1.3 version of the OS, and xcode just tells me that it isn't compatible.
Really need an answer on this one -- my app is in the final stages of testing and development, and I want to submit it to the app store on Friday.
can you install using iTunes? (drag your app into iTunes and sync))
may have to sync first and all, but iTunes should be able to do the trick for you
