Well, rumours tell us 1.0 will get the goodies first, and the other firmwares will follow suit in incremental order. So 4.1 could be a while after 1.0. It really depends if you're a patient guy, and if that 1.0 you saw on craiglist is not too expensive.That's exactly what I was thinking as well. Like you said, seeing as the dumps are already available, I figured it would just be a matter of time. Also good to know that it'll take care of game updates.
I also found a 1.0 on Craigslist and I'm curious if I should get rid of my 4.1 for it? Any REAL advantages of having one over the other? Besides some minor hardware mods that were spoken of? If all firmware are getting the same exact thing, I don't mind keeping my 4.1 and waiting it out.
