Wow, took me a while to piece it together from the thread, but I can understand all the drama. Lots of egos being hurt basically, but I'm glad everything turned out the way it did, as it benefits everyone in the long run. But basically, from what I gathered, here is the order of events in a nutshell for those who rather get the short version of the story:
Chronic Dev Team (CDT) announces Greenpoison using the SHAtter exploit to be released on 10/10/10, but only works for A4 devices.
Geohot, out of nowhere, and just days before the release of Greenpoison, contacts CDT and tells them he is willing to share his previously found exploit for implementation in Greenpoison in order so that they can save the SHAtter exploit for later. Geohot's exploit will work on all iOS devices, not just A4 based devices.
CDT is more than annoyed at this, as Geohot probably could've contacted them a lot sooner in order to implement this exploit. But CDT, having already announced a release date, is not too willing to push back the release date in order to implement Geohot's exploit, and make it sound like they will ignore his exploit and release Greenpoison with SHAtter anyway.
Geohot, by examining the latest iBoot and Bootrom code, is aware that Apple most likely is already aware of the hole his exploit uses. Which means that his exploit will for sure be plugged in the near future by Apple. But SHAtter, on the other hand, is unknown to Apple at this time. So to Geohot, it makes more sense to use his exploit first and save SHAtter for later. So in order to force CDT's hand, he announces that he will release Limera1n a day after Greenpoison, thereby burning two perfectly good exploits at the same time.
CDT responds to this by saying, in essence, "you are screwing the community by doing that, but we are not changing our plans just for you". CDT is firm on their release date and won't budge.
Geohot, as a last resort, releases Limera1n a day before Greenpoison is to be released, instead of after as he had threatened. On top of that, he makes Limera1n untethered by using Comex's user-land exploit, against what he had promised Comex. Basically, Comex had given him the exploit with the agreement that he wouldn't release Limera1n the way he did.
At this point, CDT comes around, puts their pride aside, and decides not to release Greenpoison with the SHAtter exploit, and instead puts their support behind Limera1n. Since Limera1n was rushed, it's buggy at first, but it's improved rapidly to help iron out the bugs.
So what is the end result? A better future for the Jailbreak community. SHAtter is saved for a later time, and will not be burned in the end. Cooler heads prevailed, and it only benefits us, the community.
It's quite an interesting story to say the least.
