Interesting web based application in the form of makeappicon.com The simple idea is to slip in your 1024px icon master then makeappicon hurls out a number of popular app icon size for both iOS and Android.
I tried it 'oh so quickly with my simple grape iOS app icon and it gave me 10 new app icon sizes in about 3 seconds.
Please note that I have not opened up and checked these individual files for quality, signs of degradation or other 'too good to be true' unwanted pixel scenarious.
I always create each app icon size manually so as to be able to ensure the whole pixel-fitting is in order, and would hazard a guess that makeappicon.com wouldn't be able to automagically do this.
However, even if the individual icons are not 100%, the fact that you have a simple and quick means to knock out some provisional app icons for testing etc is a huge potential time saver for when you are at the early stages of the icon design and just want to get a quick feel for how the design will look in-situ and at smaller sizes. Plus, even if you don't want to rely on it for individual icon sizes you still get a quick way to get an iPhone phone mock-up with icon in place with text.
It's definitely worth a go especially as it's FREE!
