I can't buy albums on iTunes Store?

Last week, I tried to buy an album on the iTunes Store using my iPhone, but it showed me an error message saying that I couldn't. As I had some connection problems, I thought that was the cause.

Ok, some days later, my connection problems solved, I downloaded some singles normally.

But today, again, I tried to download another album, but, again, iTunes shows me an error message, saying that my purchase could not be finished! Then, after that, I tried to buy a song from this album and I bought and downloaded it normally! So my problem is about buying albums, specifically.

Some information: I have just updated my billing infos, about a week ago. Since this update, I haven't been able to buy any album. Is this a reason or not?

All these things on an iPhone.

Is it possible to activate this disabled iPhone?

Ok so I brought this phone from eBay and it said used phone in good condition. I finally get it and when I turn it on it says iPhone disabled connect to iTunes. I tried it but it said I never had the phone trust my computer so it won't restore it or fix it. This is my first iPhone and I was trying to be cheap and avoid 2year contracts now I don't know what to do and I'm still waiting for a email from eBay about the return policy since it said no returns from seller but they lied/neglected to mention this issue any advice would help

What should I do about my future?

I'm currently in my first year of college and so have a lot of options open to me about my future career but am confused as to which path to take.

I've always had a passion for writing and cars and so am working towards my goal of being a journalist for an automotive magazine. I've done some work experience, gotten a few pieces published and have been told by a couple of journalists that I have a talent in the business.

On the other hand, i'm really materialistic. I've recently got a decent paying job at a local restaurant and since I can now buy things like clothes, car insurance and an iphone i'm enjoying having this new financial freedom. A job as a journalist for a magazine starts at £15,000 a year which is barely enough to scrape by. However, if I was to start a scholarship in quantity surveying I could be earning 30k a year while in uni then go on to 50k with a job ready and no student loan to be paying off for the rest of my life. The only problem is I don't know if I would enjoy the work.

I'm constantly told to do what you love instead of going after money and being shallow but from seeing my parents struggle with money and debt, and the fact that unless you are making a lot of money in a capitalist society you end up having to watch every penny, which I don't want to do.

Even though id love to be a journalist, the thought of making plenty of money in a job id probably succeed in really appeals to me and since i'm at this point in my life where I could pursue any career path I want if I put my mind to it, I want to make the right decision will I still can.
