you go on a website called jailbreakmatrix
No but often the device will simply not work with your iPhone, it won't break it but it just won't be supported plain and simple
Jailbreak your iPhone
Yes, you need to jailbreak your device, then download "gameboy4iphone" from cydia. Then after that, download a Pokemon crystal ROM from the internet and ssh it into your device to play, or download the ROM directly to your device from a cydia source. Google search if you don't understand some terms. Hope this helps. gb game source: http://iromrepo.com/Cydia/gameboy

1.) barrels is a Cydia app so your device has to be jailbroken. 2.) your device has to match the apps version. (Ex. iOS 5.11). 3.) sometimes it is free and sometimes it costs money. That will happen if a Cydia app gains to many downloads.
Yes but your iphone has to be jailbroken and have Cydia.
There is no Cydia for Mac OS X. Only jailbroken iOS devices are currently supported by Cydia.
I believe it is the same thing.
If you unlock it by jailbreaking it will. Jailbreaking alone does not allow you to use another carrier's SIM card in the iPhone. It has to be jailbroken and then unlocked. Once you jailbreak it then Cydia will be on the device and then you go in to Cydia and run Ultrasn0w to unlock it
