So I bought my first smartphone about a month back, an iPhone 4. It's a great phone, but I would really like to change the way the screen looks. A co-worker showed me his phone and I want to set up my phone like his. He has a lockscreen and then he has a seperate home screen when he unlocks his phone. His locks screens are incredibly stylish which is the look I want for my phone. He sent me screen shots of a few of his lockscreens. This is the look I want. I would appreciate if anyone can tell me how to do this on my phone.
