How to activate my iPhone 4 without a sim card?

My sister gave me her iPhone 4 cause she got a new one, and I just restored it cause I wanted to get rid of all the photos she had on there and apps and stuff, but when I go to activate it, it says something about a sim card and all. I don't have a sim card nor does my sister or anyone else, cause i just want to use it like an ipod, I'm not going to call anyone or anything. I can't see a skip button or anything on the page either. Could someone help? This is just an iPhone 4. Not an iPhone 4S or anything

Added (1). P.S I do have Wi-Fi at home and I've put the password in, but it goes to 'activating your iphone' then it says there's no sim in the phone.

I have bought a few television shows and films on iTunes on my iPhone and was wondering if it is possible to move these files from iTunes onto my computer so I can watch them on my PC. I have connected my iPhone via the cable to my PC but it will not allow me to drag the files on to my desktop.

Does anyone know if or how it is possible to move video files from my iPhone to my PC?

If anyone knows I would appreciate you telling me exactly how you do it.

How fragile is the iPhone 4's screen?

I'm talking about the original one that came out about 2 years ago. Ever since I first bought it, I've always had a screen protector. As of now, the screen still looks like it just came out of the box! However, my current screen protector has been a pain and has been stick out and is on the verge of pretty much peeling off on its own. So I decided on just removing it. Should I've just kept it on? Should I go and get a new one? I've heard from both sides, and both say the exact opposite of the other. Either the screen is super durable or the screen is super fragile. I realize that despite if it is in fact durable if I drop it it will most likely do some damage. Now, let's pretend that I never drop it. Will I need a screen protector still?
