Can you cancel your plan with Virgin mobile at anytime?

I'm a 17 year old student, and I can afford to get my own iphone. I want to get a pre-paid plan through Virgin for 30$/month. I was wondering if this means at anytime I can just cancel it, no commitments, nothing? This sounds too good to be true…
Also, can I buy one without my parents co-signing, without having established credit?

Hipstamatic Pictures not saving to my camera roll (iphone)?

After updating my iphone 4 to the new IOS 6 I noticed today that my pictures taken in Hipstamatic are not auto saving to my camera roll.

An iphone app I bought doesn't work. How can I get my money back?

I just bought and installed the "Christopher Hitchens" app for my iphone 4.It just doesn't work. Ok I paid only 99 cents for it but still, it's the principle. Oh yeah, all the comments on the app store(3) mention that the app doesn't work, but I hadn't read them prior, I was too enthraled to see an app about CH that I just clicked to buy.
So my question is, How do I get justice? Meaning, my 99 cents back. Can anyone help?

Water damaged iphone 3gs? The backlight won't turn on?

The phone is really dim, as in like I can't see anything unless it's held under direct light at a certain angle. I put my phone in my bra during practice today (I know, I'm dumb) and I left it out (we were on a field).It wasn't exactly raining but there was some moisture. I don't think it was completely water damaged but a lot of reasons why backlights won't turn on is because of water damage. Is there any possible way to restore the light back on? The damage is beyond the control settings. Grr…

Jailbroken iPhone 4s won't download new update?

I jailbroke my iPhone about 3 weeks ago and right now i'm attempting to download the new update. I've tried 4 different times and it's failed each time. Towards the very end at the point of "finishing update" it pops up that it failed. I've tried disabling all the features I have(I only jailbroke it to get cool customizations) and it still won't work. Do I need to remove absinthe and cydia, get the update, then redownload it?

IOS 6 deleted everything off iPhone?

My mom asked me to help her update to iOS 6 for her iPhone 4. I connected it to the laptop and made sure it synced. Then I clicked update so it would download the new software. Then I guess she clicked install or something. And in the middle of the it said there was an error so it was just going to restore the phone and install the software. After all this finished, my mom said that everything was wiped off of her phone. I made sure to sync it too. I don't understand where all of this information and apps and stuff went. I really need help. I thought you could just sync it again and it would have everything like normal.

Changed my iphone 4s to white can apple tell if it supposed to be black?

I still have warranty on my iPhone and it was black so I paid a company to get it white. But my iphone 4s is having an issue and I know they will normally replace it no problem. But my phone is now white, can they tell by the serial or something does it show up as black. Or do they just test the phone and check warranty and see if there's damage caused by you and just give you the same phone.
