... in the case where you have an iPhone app that has done relatively well on AppStore but you'd like to sell the IP over to a corporate buyer? Is there a B2B eBay for iPhone devs to sell their software?
I remember <a href="http://flippa.com/" rel="nofollow">http://flippa.com/</a> allows that. Just list your app's site for sale and include your app. Check with them.
