IPhone 4 front camera is not working

I'm using an iPhone 4 with iOS 6.0.1.
So one day, I was using the camera using the back camera. It is working 100% fine. Now, I want to switch to the front camera. And you know what happened? It froze! It is not responding! What should I do? I tried resetting it, I tried restoring it to factory settings, I tried other camera apps, and the warranty has expired! I'm not rich, so don't tell me to buy another one.

How to keep others from seeing your email on iCloud?

My friend's ipod and her mom and brother's iphones are all synced on icloud. I think they get all the same apps and stuff
so if i were to make her a gmail account, and she used her mail app to access it, would her mom and brother be able to see her emails?
of course i could tell her to just go on safari but i figure this would be easier

Added (1). Ok what so are you saying no one else can see her emails (or even know she has one) unless it's linked?

IPhone 4 Battery draining Fast?

I have a 3 month old IPhone 4. The battery could last 2 days before it was even 30% charge left. Last night and today the battery can loose 45% in an hour. I have cleared everything on it and restored it using ITunes. Diagnostics come back good, because the phone does work. Its gets hot because of the battery use. Anyone have any ideas on how to fix this or am I getting a new phone?

What could be using all so much data on my iPhone 4s?

I have monitored my iPhone 4s data uses every single day for 2 years and usually approach my limit of 2 GB right around the 5th, that is when my billing cycle starts again.

Well, in December 13th out of the blue, I get a text that says you have used 90% of your data plan, then on the 14th, it said I went over, and now today, I'm already 1/3 of the way through the extra 1 GB they gave me.

I'm doing NOTHING different and actually using data less. What can be doing this? I have no new apps.
