If i update my iphone, will i lose everything?

I downloaded some songs from Youtube because I moved to another country and my credit card doesn't work here (plus i'm too young in this country to have one, apparently) and i wanna update my iphone but it says that by updating i'll lose all of my apps and everything. Does that include the music as well? If i upgrade it will it erase all of the songs i downloaded from youtube PLUS the ones i purchased? Also will it erase my notes, pictures, etc? Oh! One more thing, how can i copy the apps and stuff to my computer? If you could please answer all of those questions in detail, i would very much appreciate it. (since i'm not that good with computers and technology in general haha) thank you.

Music won't go back onto IPhone after iOS 6 update?

Please help! So I have an IPhone 3gs and I just updated iOS 6. My music is still on my itunes in my laptop, but when I go to my iphone tab it says there's no data, and it won't let me hit the sync button and it's not telling me why. I tried restarting my computer and that didn't work. I hit restore but I'm afraid to do it since it says it will erase everything on your phone.

How to get iOS6 without iTunes update?

I bought my MacBook a few years ago and apparently it is too old for me to get a new enough version of iTunes for iOS6. I really want this upgrade for my iPhone though and was wondering if it was possible to download it without the new iTunes.

How to allow Facebook to access photos on iPhone?

I have an iPhone 4s and was about to load a photo up to Facebook when something came up saying that Facebook needs to access my photos… I accidentally hit no thanks, and now every time I try and upload a photo I get a screen that says 'this app does not have access to your photos and videos, you can enable access in privacy settings'

I just can't find where on the iPhone/Facebook I'm meant to do this.

Music similar to Fallout 3 Songs on Radio?

Fallout 3 is one of my favourite games I have ever played and one of the things that made the game so enjoyable was the songs on the radio.

Thanks

IPhone 5 set up/iTunes problem

I'm currently trying to set up my new iPhone 5. My iTunes gives the error: "You can't use this iPhone with iTunes as you need version 10.7". I have downloaded 10.7, but then that won't update because my computer says, "you need version Mac OS X 10.6.8 or later".

However, and here's the catch: the software update function on my computer says everything is up to date and there's nothing to be installed! What do I do?

Thank you!

Added (1). I have connected it to Wi-Fi, but I'm trying to do a restore via iTunes. This is my problem.

My iPhone won't recognize my home Wi-Fi?

For some reason my phone doesn't connect to my home Wi-Fi anymore. When I go to settings it doesn't list any connections available for me to connect to. Is there any easy way to fix this problem? I really don't want to and don't know how to mess with my Wi-Fi router or whatever it's called.
