I am releasing things but the memory seems to still be there according to instruments. Am I just releasing the pointer and not the actual data? How do I release THE DATA in objective-c?

The only place I can think to change is the version in my Target Properties. However, I would assume this is supposed to go somewhere in my Info.plist file as well? If not, how can I read this version info into my app at runtime (if it's in the plist somewhere, that's no problem). ...
