A while back we brought you a look at Preview Maker — a jailbreak app that allows you to doctor up your screenshots with the body of the iPhone.
That app continues to work well, but what if your device isn't jailbroken? Of course, you can always fire up Photoshop, but there is a much faster alternative, and it's dedicated to making your iOS screenshots look better.
Screentaker is the solution to that problem. It's a Mac app that has been available for some time now; perhaps you already use it? At any rate, it continues to be one of the simplest methods for dressing up iOS screenshots, making them look more professional.
