Hello, Phil here, since all my friends have now gotten iTouches or iPhones, i've been asked like billions of times if I could make an app for them. So, I decided to install the iPhone SDK/ Xcode thing to start programming. However, when I get to the 4th installation stage (Destination Select), I get this error when trying to select my hard-drive. And yes, my mac is version 10.5.5. Anyways, I have a picture below for better understanding. I would be really grateful if someone could help. Thanks, Phil.
