My iphone 5s' cameras have both stopped working?

About 2-3 days ago my front-facing camera on my iphone 5s stopped working, and now today the back camera has stopped working also, so whenever I go to the camera application, it just shows black. The only thing that has happened to my phone is that it got a little water in it about 2 weeks ago, but both cameras were working fine. Any suggestions welcome.

Just reset iPhone 4S and startup takes forever?

I have an iPhone 4S that I completely reset to it's factory default. Now that the reset has completed and the device fully powered down and has tried (well, been trying) to start up again, it won't turn on. There's a dark loading screen that's been going on for a solid two and a half hours now. It's supposed to be powering back on and displaying the traditional "Welcome to iPhone" setup screen, and it usually is only supposed to take a few minutes at most. Is there any solution to this?

Do I have to unlock an AT&T iphone to use on Cricket?

IIm thinking about buying an AT&T iPhone to use on cricket. My question is: do i have to unlock the AT&T iPhone to use it on cricket? I have checked some IMEI numbers from AT&T iPhones on Cricket's site and it said it would work but would it read the SIM card?
