IBooks won't let me purchase a book?

I wanted to buy a book through iBooks, but when I tried to purchase the book through iBooks on my iPhone, a message popped up saying "Your Purchase Could Not Be Completed. For assistance, contact iTunes support". ITunes support was no help whatsoever, and I tried purchasing the book multiple times. I deleted the iBooks app and redownloaded it, I restarted my phone, I tried buying the book on my computer but NOTHING will work. Does anyone know how to fix this problem?

Entered info to one of those stupid free iphone things?

I know this is so stupid, but I'm a really paranoid person. I entered my info like address and name and phone number and email to one of those win a free iphone things. I don't know why, but what's the worst that could happen? I'm frankly not too worried because I guarantee thousands of other people have done it too, but still. & Please don't be mean about it, I didn't think about it at the time.

Thank you.

Added (1). Also, if you can't tell, my question is what is the worst that could happen?

Transferring data to new iphone?

I got a new iphone 5s today but the guy in the shop skipped the set up meaning I couldn't restore my data using my iCloud account as their Wi-Fi in the shop wasn't working. Is it possible for me to restore my data etc… Even though I can't use the initial setup now?

I can't put anything on my iPhone anymore?

I was just syncing music to my iPhone4S and everything was working fine. Suddenly, a whole album just wouldn't go. I dragged it over to my iPhone and nothing happened. I tried again, and it said "updating", but nothing happened. I made a playlist and tried to transfer that, and the playlist showed up on my phone but was empty. So I made sure I had set it up to manually sync, and I tried all of that again, but nothing happened.

A couple of times when I tried to transfer the album, it said "adding duplicates", but the songs aren't on there =P

So I tried syncing other songs to see if it was just that album, but nothing happened So I deleted songs that I had just successfully put on my iPhone and tried to sync them again to see if I just had a boatload of broken MP3's, but when I tried to sync those songs… Nothing happened…

I'm using iTunes 11.05.05

Charging is not supported with this accessory fix?

I have a iPhone 3GS, and I have a very strange problem. There's nothing pluged in, yet the lock screen is replaced with exclamation mark, and "Charging is not supported with this accessory" is written below. I cleaned the port already, with no result.
When I connect my phone to PC, the "charging is not supported with this accessory" message appears and disappears all the time.

I have the original charger and cord.

But when I plug the phone directly into the charger, it works.

Oh, and my iOS version is 6.1.3.

Is there anything I can do about that? Because that exclamation mark is starting to annoy me…

Should I get rid of my cds? Becoming obsolete by 2014?

I know there's a bunch of questions like this already even back from 2011 wondering if it'll be obsolete by the year 2011-2012 cuz of digital music slowly taking over. Even though I still sorta buy cds still, I was wondering if I should get rid of mine. Only cuz today I heard a lot of the new 2014 cars are ditching the cd players in the cars cuz of everything going digital for music, so they putting in the usb/aux thing to plug in ipods and iphones (and this is supposed to be standard like cds players & cassettes were standard). If this is the case, I feel like I'd be wasting my money if I can't play it anymore. I still have iPod and use it regularly more than cds, but I use cds as well sometimes. Maybe I should put my cds on iTunes and sync to iPod? This is why I'm starting to think cds are becoming obsolete now after hearing this today.

What's everyone's opinion? Should I get rid of my cds? Should I be converting them to digital?

My Iphone 4s won't charge! What to do?

My Iphone 4s won't charge I have tried connecting it to my computer, to the wall and to my car charger. When I turn it off it's as if it died and I put it on the charger so it will have the battery sign and then it will turn back on but it won't charge. When I woke up this morning it started charging until I moved it and now it just won't charge. I've been messing with it for the past hour. What do i do?

Added (1). You guys please read the question carefully! I tried it with a normal phone charger AND a car charger, these are two different chargers. Please keep this in mind before answering the question.

Would iphone 3gs work better on at&t network?

I ask this because i use t-mobile and use an unlocked iphone 3gs and the data seems very slow all the time, very little 3g speeds, always edge (2g) speeds, annoying, my galaxy s2 phone is always super fast data speeds all the time.
