title: How to remove previous versions of Xcode
body: <p>When the 3.2 beta of the iPhone OS first came out, Xcode for 3.2 had to be installed side-by-side with the version for 3.1.2.  I installed the new version (3.2) in /Developer and moved 3.1.2 to /Xcode3.1.2.  Now I want to get rid of the old version and just use the new one since we can do that now.</p>
  
  <p>I ran the uninstall tool at /Xcode3.1.2/Library/uninstall-devtools and uninstall-developer-folder, but the directory still exists and has lots of stuff still in it, adding up to about 5 GB.  At this point, am I safe just deleting the folder if I want to totally get rid of it and still use the /Developer folder?</p>
  
  <p>(At about 8 GB, it's got lots more in it, but I'm not sure if that's just because it's larger or because the old version was 8 GB before I ran the uninstall tool)?</p>
