iPhone 5 Apple Invites!

This image is currently spreading like wildfire as its the official iPhone 5 press release invites!(Sadly the postman has come today and mine isn't here yet) While looking at this I realised it was rather boring, just some simple apps, but as I looked closer I realised it was in-fact a puzzle! I've mangaed to solve most of it, but does the phone symbol mean that only one piece of hardware will be coming out?
