Can we have a new "technical" sticky?

Seeing that all these methods have been moving towards "black box" tools. Doesn't anyone know a good source as to the technical backgrounds surrounding the various hacks? This might be good to know when troubleshooting various problems that arise.

For example, what is the mechanism of activation, unlocking, jailbreaking, etc etc.

I know the answers are probably buried here somewhere, but a comprehensive guide would be awesome.

As I side note, my iPhone seems to stop taking in/out calls when I go "out of service range" and back. The only thing that fixes it is a reboot...
