This is exactly what I wanted to know, thank you.

I'd like a quick clarification before I start this. I have a 3g on BB 5.14.02 and 4.1 firmware. I want to end up on BB 6.15 with 4.2.1 firmware. Am I understanding correctly that I should choose update normally in iTunes first, then select the 4.2.1 IPSW with redsn0w?

Well, they were faster with redsn0w than my VMWare download so I'm just gonna use that and cancel these downloads for now. On the plus side, I'll finish up those downloads a little later and I'll have it ready if I ever want them again later. :)

Yep, same here with a bit less than an hour left to go. I googled around and I've seen mixed results about success and all of those were very old.

I'm sure I'm not the only one to have thought of this. Has anyone tried using VMWare with an OS X image with success?

If I'm not mistaken, you should be able to run pwnagetool by using VMWare or similar. I haven't actually tried it yet, but I'm downloading the necessary files to give it a try unless they release the new redsn0w before I finish... it's gonna be a few hours to download all these files on my 3 mbps DSL.

There has been an explosion of new informative posts on MuscleNerd's Twitter today. In particular, this comment was exciting:

"Finally got ultrasn0w working fully on 4.2.1. Apple inadvertently(!) broke ultrasn0w via aggressive compiler optimization"

It sounds like this is probably exactly what we've been waiting for. Sounds like the release by Sunday estimate might be right.

People aren't going to realize this is sarcasm.

It boggles my mind that so many people don't get this. There are a ton of reasons.

First and foremost, it is a testament to the tremendous number of people who are awaiting this release. These people are excited, anxious, and there are bound to be a few that skip over a sentence or two. Expecting anything more than simply skimming over the comments section is just plain silly, and the chances of missing something there or on twitter are high.

Secondly, in relation to the first reason, there is a very apparent language barrier. As I've followed this, I've seen a very large number of comments that have varying levels of command of the English language. To expect these people to be able to fully comprehend the text is plain ridiculous. They are most likely putting forth more effort than us native English speakers in an attempt to understand, and they can't even ask questions in their native language without having them deleted, so they turn to rough translations or babel fish.

Third, yet again related to the first, there will always be a few people who only skim through the text and then ask a question instead. They could be lazy, or they could be intimidated by the technical jargon. Remember that many people might not even know what jail breaking even means. As a programmer who has installed at least 3 custom firmwares in the past and worked on a development team for a game bot, it took me a fair deal of research to figure out what I need. There is a lot of misinformation from other sites going on making this even worse.

Frankly, considering the extraordinarily large number of people that are commenting, and the high level of anxiousness they share, the comments have been surprisingly civil. So instead of treating these people like the scum of the earth, why not give them the benefit of the doubt instead of crying over spilled milk?

I'm guessing that is precisely the reason it hasn't been released yet. They've supposedly been sitting on this unlock for months, so it doesn't follow that they'd need to test it this long for an operating system that had already been released during that time unless they've added support for features related to 4.2.
