ITunes Store shows no music or my purchases?

I just installed the very newest update to iTunes. I'm able to play and listen to music from my computer just perfectly fine, but their Store is not working. I can see their front page, like everything that's being advertised is showing, but whenever I try to search for a specific Artist, there's absolutely no music showing up. I also then try to see my "Purchases" on my account, NOTHING is showing.

Other people who have asked this were using an iPhone, however I do not own an iPhone or ANY smart phone with apps for that matter. I'm using my laptop as I speak, and am experiencing the same issue.

Some problems I have with my iphone 5s?

I have some problems with my iphone 5s that would like to state here hope to get the solutions for them:

1- My iOS version was 7.0.2 and I installed some good apps on it, then I updated my iOS to version 7.0.3. After that when I tap some of my apps, first page of them appear and then they immediately vanish and don't go to the app, in other words, they don'r work (some of them of course). Does anybody know how to solve it?

2- I should recharge battery in what (5, 10 or 20) percentage?

Why do people keep saying Verizon doesn't use SIM cards?

Okay, everywhere I read- I see people posting about how Verizon doesn't deal with/use SIM cards. Why do people say that, when it's a flat out lie? If you look at an iPhone from Verizon, or a Galaxy S3 (I don't know if the S4 is the same) Are the SIM cards just there to take up space? Or am I missing something on why people say that Verizon doesn't make SIMs?

Added (1). Given the information below- Can you use a Verizon sim in a non-verizon phone that is unlocked, to put it on the VZW Network?

How to delete old songs on my iPhone?

I got the iPhone 5s a few days ago. I wanted to download the music I already had on my itunes. When I plugged the phone into my computer it started the syncing process. When it was done, I checked my music and not only did it download the music onto my phone, but it downloaded songs that I deleted off my itunes account 3 years ago!

IPhone 3g won't turn on or charge?

I left it alone for maybe half an hour, it was half charged (50% battery left) and left it on my coffee table. I told my cousin to go get it for me and when I got it it wouldn't turn on. Usually it tells me it needs charged or the picture with the battery and plug on it will appear, but now it won't do that. I can't get it to come on at ALL! And really I have no idea what to do now. I can't plug it into the computer because nothing comes up, it doesn't make a noise that it responded to the computer. I have no idea what to do now. It usually takes like hours for it actually turn on, but it usually tells me that it's charging.

Will 300MB for a iPhone 4S be enough

I'm wanting to upgrade to a iPhone 4S. Service is AT&T. I was thinking about getting the 300 MB since it will only be 20$ a month. But will it be enough? I will probly only be calling and texting. And using twitter, Facebook and instagram and a couple of games. I will probly only uses my social apps when i'm at home an just use my Wi-Fi so it won't take up my data! Will it be enough data for texting and calling? I can't get any more data I can't afford it. Will it be enough? My texting and calling will be unlimited. Also how can i get my parents to let me get this phone? They think i can't afford it but i can if i get this data plan.
