Is it possible for me to retrieve my lost iphone?

So basically my phone is an iphone 5 and it's updated to the recent update of ios 7 and I only just realised that I didn't activate my icloud account and there's no lock on my phone… What I was wondering, would i be able to trace down the thief even if they deleted my icloud account and changed it to theirs and did the whole restart process ( i think it's called restoration system something ) and inserted their own sim and take out mine… Please help!

How to fix my volume and mute buttons on my iPhone 4?

Basically I dropped my iPhone 4 and my volume buttons and mute button broke. I'm not sure if there's a way to fix it or if a repair shop could fix it. I've searched on the Internet for answers but none of the answers helped, they were all about other problems with the buttons. Could you please tell me if they are fixable and how? Or how much roughly it would cost to get it done at a repair shop?

IPhone 4 keeps disconnecting from Wi-Fi? - 1

I don't know what's going on. It wouldn't be a problem except as our family splits a data plan, I only have 1 gig a month to use. It usually seems to do it when I'm watching videos, which uses a Tom of data, and then I end up going over my data allowance. When I go to Settings it says Wi-Fi is 'not connected', but goes right back up once I click out network.
