I found an a iPhone from sprint(i think)?

I found a new iPhone, a pretty nice one I think. I want to return it to the owner but i can't even look at the contacts because they locked it(which i never understood because it doesn't help them). I was going to leave it but it was raining and the phone was getting wet. I think its from sprint and i see someone who has the owner on instagram(which i don't have or know how to use). I'm trying hard to get it back but i just don't know what to do with it and no one is calling. Any Suggestions? If someone call could i answer it without the password?

Why am I not receiving text messages because of iMessage?

Is there a way I can receive texts from everyone while my iMessage is on, regardless if their iMessage is on or off?

How to copy photos from my iphone 4s folders (not camera roll) to pc?

I have an iPhone 4S with hundreds of photos synced to it from an old laptop. How do I save these photos to a new pc as I have no access to the original photo as old laptop destroyed.
I understand how to copy photos from the 'camera roll' to pc, but it seems impossible to save photos from other folders which have been synced previously.

Deleted messages on Iphone 5?

I have a habit of deleting all of my messages because I hate seeing my inbox cluttered. But it turns out I deleted a conversation I ended up really needing. I mean I don't know if I completely deleted it or not. I didn't press into the conversation and delete the messages selectively. I just swiped it to the left and deleted the thread. And i know when i used to do that, the messages would still appear when you would search it on spotlight. I don't think it does that anymore; i just tried it.

So is there anyway I can go back and get the message somehow?

How bad is the iPhone 5S battery?
