The iphone5s
I like it that they have this function like when you just turn it on, it gives you notifications that can let you know the things you need to know in a faster, easier way. Also, you can get a nice grip even if your a kid. It also has a longer screen than the iPhone 4 and you can do apps easier than just squinting looking at the screen. It is pretty sleek. If you were thinking to buy this I would really recommend it.
