An Untethered Jailbreak Process
Remember JailbreakMe? It was a jailbreak tool a few years ago that tool advantage of flaws in the Safari web browser on the iPhone, which allowed users to jailbreak their iPhones wirelessly without having to plug them in.
It was awesome, and JailbreakMe will probably remain one of the best jailbreak tools to exist.
However, it would be awesome if the iOS 9.2 jailbreak process used similar exploits so that you could wirelessly jailbreak your iPhone.
The bad news is that this is unlikely to happen, and it's probably a safe bet that we'll never see something like JailbreakMe come up ever again.
