How to take a full length screenshot of the iPhone Messages app? How can we do a "full page" (full length, from first message to the last message) screenshot?

For example, this should be the resulting image:



It's just one unified image, not multiple screenshots.

Is there a way to do this easily?

(Taking multiple screenshots and merging them together with Photoshop like what we have above is not a real solution.)
Stich It! is the App you're looking for I believe.
