Added (1). Yes I want to keep my number and activate and iphone someone gave me because they got the new one. How do I go about doing that? Do I have to go into the blackberry store? I'm not worried about the contacts and stuff, I just want to activate the phone.

Why doesn't my iPhone won't turn on?

I have a iPhone 4s and it was working perfectly fine before, i went to sleep and put my phone on the desk. When i woke up i tried to turn on my phone but nothing happened, i pressed all the buttons and tried the sleep/wake method where you hold the home and lock button at the same time, then i decided to charge it, it's been charging for around an hour now and the screen is still black and there's no sign that it will turn on, i gave up up and tried connecting to itunes through my mac, it said the usb was using up too much energy and didn't connect. I'm desperately running out of ideas and i don't know whether it's broken or not

Added (1). please answer!

How to tell if an iphone has been damaged by water?

Help!
I bought a second hand iphone 4 yesterday. The seller told me that the phone was okay and he sold it to me for £170. And now I noticed that there's a yellow thing on the left side of the screen. I don't know if you can see it on the photo, you can zoom it in if you want. Do you think this phone has been damaged by water or is there something wrong with LCD?

If something's wrong with it, i don't think it shud worth £170. It should be cheaper than that -___-

What is the app called where you can see what people do on your iPhone?
