Any examples of photos taken by Metro PCS' LG Motion 4G?

Well, I really want an iPhone, but for someone who is just starting out with contracts and stuff, I'd like to go the other direction and get an Android.So, are the cameras for the LG Motion 4G just as good as an iPhone camera would be? I'd like to see some examples or maybe even comparisons.

Finding and using a lost iPhone 5?

If I found an iPhone 5 & can't find the owner can I use the phone without getting in trouble? What if they reported it lost and just got a new phone? What should I do?
