Yes. You wii can be repaired so that you can be able to update or get apps even though your son tried to jailbreak it.
If you have Cydia then there is no point to re jailbreak. If you try to re jailbreak, The tool you try to use will not let you jailbreak it because the Cydia sources are already installed into your device.
It already is for a long time
No, because it will just get rid of the jailbreak. Plus, there isn't another jailbreak yet for iOS 6 anyways, so i wouldn't if i were you.
Yes and no. It is an exclusive application for iPhone 4S only, and it comes with it already, as the other factory apps such as Camera, Phone, Messages, Facetime, ect. You can't download it through App Store, and you won't need, if you have an iPhone 4S, as you will already have it installed. If you own an older iPhone or iPod Touch version, you can theorically have Siri installed, but only if your iDevice is Jailbroken. Search what 'jailbreak' is on google :) Hope I helped.
have sex with it then it will get installed into a mode
Redsn0w jailbreak 6.1.3 for the iPod 4G is already available. It was released in March 2013. However, if you use Ultrasn0w to unlock your iPod do not update 6.1.3.
Face Raiders is part of the preinstalled software. It is something to help show off the 3D effect, and not much else.
If you have already successfully completed the jailbreak, then just turn it on as you normally would.
It has already been released, the jailbreak provider is called redsn0w.
you just need to know how to get drivers for your wireless receiver unless theyr already installed. if they are installed there is something at the bottom right of the taskbar that you can open "wireless networks" connect anyway when you try connecting

This depends on where you purchase the Sierra Denali from. The basic model will not have the DVD system already installed, you will have to custom order it to have it. If you are buying used, it might have it installed if the previous owner had it.
