My Iphone 4s won't download apps?

I purchased my Iphone 4 weeks ago and ever since I'v got it, my app store will not download apps. I have entered my password so many times and it keeps saying 'Can't connect to iTunes right now.' I have made a new account and the same thing happen. My mother and brother both got an Iphone 4s and they are able to download apps. My mothers is a month old and my brothers is maybe 2 or 3 years old. I have contacted apple but still not have replied also my app store is turned off for cellarer, I'm connected to Wi-Fi. What should I do?

I'm having an issue with my new iPhone and iTunes?

I have a bunch of music on iTunes on my computer that I put on iTunes with CD's. I'm trying to get that music on my iPhone, but my iPhone doesn't pop up on the left hand side above playlists like it normally does, so I can't do anything. How do I get my iPhone on there? It's a 5c by the way, in case that's important. And I know that it can be done because I've done it before, I just don't remember how. Can you help me out?

How to backup music from my Iphone to my PC?

My phone has stopped working properly (a different story), however, before I go to the apple story and have them tell me that I need a new phone, I want to backup all my pictures, messages and music. I know how to backup my pictures, however I have trouble with music (as well as contacts/imessages- any help?). I have Itunes on my PC, however I have tried syncing my phone with the computer, and followed many instructions for backing up music, none of them working. Please help! I have over 600 songs that I've bought over many years, and definitely do not want to lose them (I also do not want to lose my contacts or messages, please help) Thank you!

Why didn't I get the iphone updates? How do I get them?

I have an iPhone 4 for Virgin Mobile, and I never got IOS 8, and a lot of my other friends got it. And then Apple put out another update called 8.0.2 to fix the bugs from 8.0, and I didn't get them one either. I went into my 'general', then my 'software update' and it still says '1.7.2, your software is up to date'. So why did I not get either update, and how could I get the new update?

IPhone 6 VERIZON wireless phone plan?

The guy at Target told me it would be cheaper to go through Verizon as a one-line 2 year plan user. He said it would be like $199 for the phone [plus tax so its like $200 something] then the activation fee, which is like $40 or something, and then the $60 a month for a 2 GB data plan.
As you can see I don't need a lot of data because I always go to places that have Wi-Fi. My house, restaurants, even church, and work., so I don't need a lot of data for when I'm not where Wi-Fi is.
HOWEVER, my problem is that the website for Verizon doesn't offer anything below 16GB…
Does a plan below 16GB even exist?
