Front camera on iPhone 4 stopped working?

I've tried replacing it to no avail. I've tried a soft and hard reset. I've cleared memory, I've turned on and off in restrictions. I've tried the "cover the sensor up" thing, didn't work. I've closed apps I wasn't using, that didn't help.

Here's my problem. I'm using straight talk so if I update I need to make sure I can re jail break and unlock it again. Most of my contacts use iPhones so without iMessage I'd have no way to contact them. I'm scared to reset and loose everything. So someone with experience with this please give me some advice. If I update is that a likely fix? And if so will I be able to rejailbreak and change apn and use Cydia?

False alert: Snapchat screenshots?

Yes, I admit it- among the stupid things I've done, I've send a nude or two via snapchat. I trust my boyfriend, and I know he hasn't screenshotted any of them. Why? Because he wouldn't dare (because it's me), because he has trusted me enough to reciprocate the sending of these pics, and biggest of all because he's in the military and such stupidity would ruin his life, and he knows it! Why did it say he screenshotted a sext of mine? He swears he never did (he could be lying), and he sent me a series of pics which cover (what he says are) all of his iphone pictures. I'm unsure of what is going on, but I had my face in the shot and I'm very scared of the implications that has.

What sort of USB hub do I need? External laptop Keyboard/Mouse?

Question is pretty self explanatory.
I need a USB hub for my laptop to run an External keyboard and Mouse. ( 2.0 )
Encase it helps to know the power requirements, I'm using a Ttesports pro gaming keyboard and Razer Naga Epic mouse. I'm running a g74sx Asus laptop if that helps (two of the four usb ports have died T_T) of course it would just make sense for me to use the two current ports but I also have my iPhone and Razer Nostromo plugged into those, thus I need more room.

I require at least 2 more ports via said adapter.

Please post link to suggested adapters/hubs.

-Thanks in advance

Me and my four friends have a four way chat on fb and one of my friends was saying all this stuff but we found out it wasn't her on her account, we clicked on the message to c if it had a location because sometimes on iphones you can enable location services, and it only said 'sent from messenger so over someone's phone, she wants to go to the cops will they be able to get an IP address on the message, plus the message were deleted off her account only us three girls can see them and she also got out of other sessions on her fb which i thought was dumb because the police could've used it.

What do I do to design my own iphone case?

I have a clear case I bought from amazon for my iPhone 4. I figured I could design my own case whenever I wasn't by putting different pictures in between it and the phone. The only problem is what dimensions and/or programs do I use? I have the windows 8 and it has the option of different sizes I can print if any of those works and paint if I need to change the sizing.
