My iPhone 4 won't turn on

I was going to take a picture with my phone and then all of a sudden liveliness start flashing, so I exit to home and it continues to flash blue lines, then it turned to a brown screen. In panic I turned my phone off hopeing it would help but it hasn't turned on since. I just got my phone 3 days ago and I don't know why this is happening? Someone please help!

Try plugging it in and holding the power button and the home button until you see response (10-15 secs) if there's no response, take it back into where you got it and have them replace it.

You might have gotten a lemon, but try doing a hard reset. If you take it to your provider or a tech store, they might be able to help.

Never heard of that happening, but if something is wrong and reboot won't help then just take it back and they will give you a new one
