BOOM. You're done. iPhones try to act like it's "just a website bookmark" because they want everyone to go through the App Store but really it functions just like an app... Full screen, moveable icon on your home screen. All of it.
Enjoy.
Install the Channel 3 app from the Google Play Store.
Yeah I have this one too (in limited edition purple!). You can even hook this up to a TV and play off of that if you want. Almost all the carts for the handheld work for the console (a few don't because of licensing reasons but again, only like 2). Nicely made, good design, and a whole bunch of games to play make for an excellent retro handheld.
