True if you want to game the system - if you actually want to help them test out there service just upload 5gig of photos and video - I'm sure most people have that?
For me, I already have all my gigs of photos in DropBox, so I had to come up with a way outside of uploading all those images again. I unlocked the first 2GB or so with legit iphone images, but to get the rest of the space, used this method.
