What is going on with my IPhone? - 2

I have an IPhone 5 and just recently this weird thing started happening.
When I open my music and click a song, it plays the song right before it rather than the one I clicked. It only does this when I'm selecting a song which is confusing me. I've tried turning my phone off and back on (I can't restart because my lock button is broken and assisted touch won't do that), and syncing it with my computer. Does anyone know what is wrong/ how to fix it or am I just better off taking it to the Apple store and seeing what they can do?

Can I sync music from iphone into itunes library? (music lost)?

I recently lost everything on my computer due to a virus so i had to reinstall itunes.

When i logged into my itunes account my purchased music was there, but i was wondering if there was any way i could get my downloaded music back into my library without locating the folder on my computer bc that got erased too.

The online music is still on my phone & ipod but i would like it in the library too.

I would appreciate any help or advice, thanks.

Buying a SIM card in The UK?

I'll be spending the upcoming semester studying abroad in London. I'm very attached to my phone and I have to bring it with me to stay connected back home. A friend of mine already arrived in London and said that I wouldn't be able to buy a SIM card for my phone at all because my American credit card doesn't have a PIN number (that's what he was told by the representative at the Virgin store).

I'm wondering how I can get a SIM card for my unlocked iPhone. I would be looking for either a "pay as you go" type SIM card or a month-to-month SIM card because I'll only be in the country for 6 months. Any speculation as to why my credit card may not be able to purchase the SIM?

-looking for a SIM only plan (carrier doesn't matter to me)
-have a chip-and-signature card that doesn't have a PIN number
-looking to buy it when I arrive in London from a store rather than online

How to get my songs from my iPhone 4 to my computer?

I used to have almost 1000 songs on my old laptop and that would be my source for music to my iPhone, however my laptop broke a few weeks back and I have now begun to want music from my current laptop, however whenever I go to put these songs onto my phone, I have to sync and that would mean deleting the 1000 songs I still have on my phone and I don't wish to do that. I have been looking for a solution of getting those songs from my iPhone onto my computer but every time I almost find the right solution, I have to download something to help it work and considering this isn't my laptop I don't want to risk any viruses, so i'm wondering if there's any way of finding the music from my iPhone and transferring it to my computer.
All and any help I appreciated, thank you.

My iPhone 4S sound won't work?

I have my volume all the way up and the switch on the side isn't showing the red and if press my volume buttons nothing pops up on my screen. It doesn't work when I have my head phones in either. I can't hear the keyboard clicks. I can only hear if I get a call or a text. I don't know how to fix it!
