How to enable your privacy settings?

I'm not sure if I'm asking this quite correctly, so let me explain further. I have an IPhone 4s. If I were to go to settings, then go to the "Privacy" part, and then under that "Photos", I can't do anything. I can't switch to "on" or "off" it would not let me. I'm not exactly sure if I'm explaining this correctly at all, but if you do understand what I'm saying, then please answer me question. I can't post photos at all, like on instagram, facebook etc. And if I were to go to settings, and then try to turn on photo privacy I can't.

Is iPhone 5 only 4G or is it 4G and 3G?

I'm not entirely sure what 4G is. When I get my iPhone 5 my mom will add me to her plan (wich also includes my dad). They have 3G but have an iPhone 4.So when I get mine will it be 4G?

Added (1). But do I have to pay extra for it or will it just be there if there's a 4g signal?

I cracked the front of my iphone 4 screen. I called Verizon and it costs to much to have fixed/replaced so i thought i could buy the kit off amazon with like a cool blue screen or something.

I dropped my iPhone 4S and it turned off. I plugged it in and it came back on but if I plug it out it turns off again. While it's plugged in, it keeps turning off and on even though the battery's 100%. I know dropping it messed up something on the inside but what can I do to make it usable? Or any other suggestions?

Iphone 4 locked says connect to Itunes?

I changed the passcode on my phone at night and forgot it in the morning. I tried too many times and I'm locked out. I have never connected it to itunes before but I'm logged into my apple account on my phone. When I connected it to my computer and logged on itunes it said I have to unlock my phone but this is not possible. How do I reset it and would all of my texts and pictures be deleted?
