This is probably a really dumb question, but I just now downloaded and installed the iPhone SDK from Apple's site. It seems like the installation completed successfully and it asked me to restart. However, when I tried looking for the actual SDK and the other apps it's supposed to give me, it's absolutely nowhere to be found. QuickSilver can't even find it. Am I missing something? Do I have to connect my iPhone and activate something before I have access to all of this? I'd really appreciate any help.
