These guys are lame while I appreciate what they do release what you got don't penalize the guys who are already on board if you are good hackers you get the 7.0 out then the 7.1 then 7.2 and on. If you have the tools make the current group happy and get started for 7.1. What's the point of waiting 5 months so that your break can cover .0 and .1? get the .0 dont penalize the early birds. I think they don't have anything, or their hacking skills lack and they are nervous about their ability to get it again (.1). so they just wait and cover both
Because this is not their job, they are not living from it. Maybe if you pay them a fixed salary you can then maybe get some jb per each new fw update. FYI some stuff that is found in older fw CAN be used and is used in newer fw since they have not been patched and thus is part of the reason, to save what you have and release to as many people as possible. hacking and jb is a community driven thing to help many not a few.
I also think you should release your own jb since you know their skills are lacking.
