Before I update to IOS 7, should I backup my iPhone 4S?

From what I read, the new software makes things better. But I'm afraid that I'll lose the 8.9 GB used up. To clarify i'm afraid ill lose that all my photos, apps and contacts will be completely gone after I update and I can't use iCloud because its not enough space. Where and how can I backup my memory and I can get it All back after I update.

IOS 7 fault downloading on iPhone 4S?

Ok so I have an apple iPhone 4S with more than enough room to download the new update, there's nothing illegal on my phone nor is it an insurance rip off, I have followed the instructions to download an my grandad who has the same phone is having no problem downloading it, we also live in the same house so it's not signal, so why do I keep getting a message saying there's a fault downloading?

Why does iOS 7 show me songs on my iPhone that I've deleted?

So I got the new iOS 7 update for my iPhone 4, and aside from the fact that I'm not sure whether I like it or not, (though I'm sure I'll get used to it somehow) I noticed that on my music for some reason, its coming up with songs that I've deleted, and I know I have deleted these songs, yet they keep showing up with a download symbol next to them, and I can still listen to them, its bizarre, does anybody have any idea as to why this is? I know iOS 7 has only just came out but I'm hoping someone does know a little bit about it in depth to give a good enough answer!

I want to delete IOS 7, how?

I'm having trouble installing it and it's taking up too much space so how do I uninstall it? If I decide to keep it, when will the Apple servers be fixed? And after I install it, will it still take up as much space as it does now? I have an iPhone 4.

When will the update for the iPhone finally work?

I have been waiting for hours just for the phone to verify the update process. I delete majority of all my applications to have enough MBs for the update. Why won't it load?

Jus uploaded iOS7 and all my photos are gone

I'm so stressed right now! I've just updated iOS7 on my iPhone 4 and all of my 9000< are gone! Just missing!
The main thing is that on iTunes it showed that there still was 14gb taken with photos, but now (after ~5mins) it shows that "the others" is 14gb.
I'm afraid to click to iCloud because I don't think I saved anything there, and I'm aslo afraid to re-start my phone…

My iPhone 5 won't connect to Wi-Fi? - 2

I enter my security code correctly. I know it's correct because it doesn't show "Password Incorrect".
And the load wheel just keeps spinning beside my Wi-Fi. I look at my moms Wi-Fi and it shows a check mark for her. It has acctually been using up alot of my data. I turn my data off and keep my home Wi-Fi on and i have no internet connection. And beside my phone company it just says 3G. I updated my phone just now to iOS7 and that didn't help either.
