Is 500mb for a data plan enough?

I'm planning on getting an iphone and i'm wondering if 500mb of data would be enough. I spent most of my time at school & home where i have Wi-Fi. So i wouldnt be using data as much, just occasionally in case i need it. Would 500 be enough for me or no?

My iPhone 4S won't make sounds?

It somehow got wet I guess because there's a little part in the corner of the screen that looks odd. It says there's headphones plugged into it, which there isn't. The only time it makes noises is when you go to settings, sound, and adjust the sound there, where it plays the ringtone. And it also makes noise when I call someone and its on speaker, and listen to voicemails on speaker, etc. Music and such doesn't work unless I have headphones in… I've turned it off and on about 50 times. I've also turned it off by holding the home button and the power button down. Nothing. Should I just take it to the verizon store and see what's wrong with it or is there something I can do?

How much data does apple maps use on iPhone 5?

I'm wondering if apple maps uses a lot of data and how much it uses. I will have a 2 GB plan and don't want to use up a lot of data using the map program. Specific numbers would really help but just in general would do good too.

Can I change my iPhone color from black to white for free?

I have the black iPhone and I really want the white iPhone. I got the black iPhone because it seemed like it wouldn't get as dirty but I have been reading that it gets dirtier easier than the white one. I have Verizon and I was wondering if they would let me do a swap (with the exact phone, no difference except color) with no cost or a small fee. Also if they let me do this, would I have to start a new plan? My plan is over in September and I do not want to get a new plan.

My iPhone 5 battery drains during lock?

Whenever I sleep, I never charge my iPhone, so it's basically next to me on lock. I think I slept to it being 38%. I slept for 11 hours (yup, I'm a potato.don't worry, this was only yesterday) and the next morning, I woke to the battery being like 25%. Just wanted to know if this is normal?
