Starting with the Home Screen I asked one question that apparently hasn't been asked too often - how come the dock is that little shelf, on which there are 4 icons resting, but all of the other icons don't have a shelf of their own? Either we pretend we have gravity here, or we don't, so I removed the shelf and replaced it with a much simpler dock. All the other colours are matching the device colours, creating a clean, simple look.
In Safari I was afraid, that white version would blend too much with the device, because most websites are white too. It might look like that, but I tested it in real life on the device to see, that it doesn't blend all that much anyway. Takin it into account I created the two monochrome Safari versions seen above.
Mail was a bit harder - I decided to remove the Inboxes and Account containers - I do know the usability idea behind it, but people adapt and after 5 years of introducing the interface they don't need aditional vertical lines to know which part belongs where. Taking that into account I created the black & white versions and added a dominant colour - blue to better indicate the amount of messages in each inbox, because in the end that's what we look at when we launch the app.
In Messages I decided to keep the green, grey and blue speech bubbles, but change the buttons and backgrounds, because while focusing on the messages everything else should simply 'disappear'. Some slight changes to the type were made as well. Without changing a lot, we have a completely new Messages app!
