Will apple update my iphone (3g) for free?

Since my computer won't let me update my iphone saying that it is inactive/error or something, i have pretty much given up. I kinda want instagram pretty bad but i haven't updated my iphone in 3 years, the ios is not updated enough to let me download instagram or any current app in general. My facebook app is so outdated and there's so much features i can't use. Will apple update my iphone for free or will they charge me a fee? And are they even willing to do so?

Added (1). I don't even think my iphone is an ios 4.1.2. Its mostly likely an ios 3.

Why does my Iphone 4s have 6 gigs taken up by photos?

I only have 860 photos on the entire phone and a few very short videos. I have checked the files in the DCIM folder to see if there were some in there that were not showing but there's only the 860 listed. I have no idea how 860 photos could use up that much memory. My friends Iphone has over 2000 pictures and only 2.5 gigs are taken up.

Iphone 4s stuck on boot logo?

Replaced the screen. With the broken screen it worked fine. Now it stays on the apple logo. It won't go into DFU mode, itunes won't recognize it, and I can only turn it off by disconnecting the battery. The only sign of behavior i've seen is the little logo that says to plug it in to charge. Sometimes the screen flashes white when its plugged in.

How to know if I'm driving sober?

I'm almost 16, and about to get my drivers license. If a situation ever comes up where my ride home has also been drinking, I want to have a picture of a chart that calculates your BAC (blood alcohol content) on my iPhone, like ones that factor in weight, time, and amount of drinks, and any other factors. I want something that is accurate and easy to use. I'm not planning on drinking under age, but it's possible that this situation could come up with one of my friends. I just want a reliable website where I could get a good example of one to have a picture of on my phone.
