To be fair, redsn0w had this first. They already have an untethered 4.2.1 with the exact same stipulation... mac only.
It seems irrational to release the untether exploit now, since 4.3 is on the horizon. Still, I'll certainly enjoy finally getting a free "Find my iPhone" account once they roll out a Windows version of this (that works).
Also it's worth noting that this release is apparently buggy and isn't working for most users. I'd hang on for a day or two until they iron out a few of the bugs.
I'll remain on 4.1 for some time before upgrading to 4.2.1 or 4.3.
Seeing how bad many tweaks and apps perform in combo with newly released FW-updates I plan to stick to 4.1 until I'm absolutely sure every bug is ironed out.
what about windows users ?
According to their twitter it's expected to be out by midway through next week.
Edit: it's out now.
