IPhone 4s light won't turn off?

My iPhone got wet and this light on the back of my phone by the camera won't shut off! Even when I turn my phone off. This is going to KILL my battery and I tried everything!

What's the catch with Virgin Mobile's Beyond Talk Plans?

How the heck does Virgin Mobile keep its prices so low? Is there a catch to Virgin Mobiles low plan costs?

I'm thinking of getting the iPhone 5, and from what I see, you're paying for the whole phone upfront, but you only have to pay $35 a month for unlimited text and data and 300 mins (I rarely even use 100 mins), but I don't wanna get anything that will make me worry financially. So is it really as simple as it sounds?

Pay for the whole phone cost ($550, so you actually get $100 off from the original $650) and pick a plan of $35,$45, or $55 a month, and it's contract free.

Oh, one more thing, how can virgin mobile also provide an iPhone 5 for such a low cost, $100 off its competitors price? Is it because you have to pay for the total cost upfront instead of over the course of 2 years?
