Free up valuable hard drive space by getting rid of unused iPhone Apps in iTunes

I was trying to discover what was taking up large amounts of space on my MacBook Pro; while investigating I discovered that there was a little over 15GB of iOS apps in my iTunes folder.  The vast majority of the apps that were on my Mac weren’t on my iPhone, therefore I wanted to get rid of them.  The issue I ran into was trying to figure out if I could safely delete these iOS apps.  Fortunately, I discovered a nice write-up from the from Chris on the OWC blog that I was able to successfully follow and I figured I’d share it with others.  Go give it a read, it could save you a few GB of hard drive space.
