Got my 3GS on release day. It's my first iPhone (and my first Apple product). It has exceeded my expectations - but I can't say the same for every app I've purchased. What's the protocol in such a situation? Does the app store have a returns desk? Can I sell my used, unwanted (but PAID FOR!) apps on Craigslist? What's the deal, here? Googling for this returns nothing useful; I can't find where this has ever been discussed. Surely people don't just buy an iPhone app, figure out that it doesn't meet their needs, then uninstall it and say, "Bummer. Ten bucks down the drain." Do they?!
