I've just update my version of Xcode to 4.2 - Xcode has given me a load of warnings from the Three20 source. - So I guess the version of Three20 I have must not be compatible with iOS 5? I'm using the recommended shared directory layout but have manually downloaded the files from the zip, not using git. Once I have re-downloaded the files into the shared directory, should I do anything else to update my project - run the Three20 python script?
