Even if I had an iPhone, I wouldn't use any of these services and would use cross-platforms alternatives instead, when possible.

The first thing he did with it? Run minecraft with a visibility setting that ate up all 16GB of ram.
I find this comical, I've never played Minecraft but what I've seen of it looks like the graphics engine was borrowed from the original Castle Wolfenstein 3D.
