Should I let them use my personal hotspot?

So I have an iPhone 5, and it has a personal hotspot. When i connect a device to it, i guess it let's them use my internet so they have internet or service.

I'm in High school, and I take the bus in the morning. And there's this guy I sit near and I let him use my personal hotspot on the bus ride cause his iPod doesn't get internet. Where pretty good friends so it's not like its just some random guy.

But it just dawned on me, should I let him use it? Is there any risks I'm taking by letting him use it? Should I stop letting him use it?

Just wanted to know and be sure.

How to create a bright white background?

So I make duct tape wallets and was looking for a new way to take pictures of them to post on my Instagram. I've been trying to make a really bright, white background to where it's pretty much invisible, but to no avail. I've seen a couple of different people's posts who have done it and I think it makes the product stand out nicely. Since this is just for Instagram, I'm just using my phone, nothing fancy. It's an iPhone 4S if that matters (I guess if you list any apps). I have a white background and a lamp that produces a bright white light. Will I need more than one light source?

Just wondering if anyone can give me some tips on how I'm be able to achieve this.

My security settings won't let me download the new iTunes?

Okay so I just got an iphone 5C and I backed up my old iphone and when I went to plug in my new 5C to the computer it said it requires the latest version of iTunes and when I went to download it off the apple website my computer says that my security settings will not allow it to download. I have already tried lowering them in control panel which didn't work, I tried to add the website to the list of trusted websites in control panel which also failed, I also tried to change it on the tool bar in internet explorer. I'm pretty sure it is windows firewall that is stopping me because Norton says it is okay. So how am I to download iTunes now?!
