iPhone OS 4.0 beta 3 is ready for your scrutiny (update: it's back!)

The last time Apple dropped a release of iPhone OS 4.0, it left more than a few downloaders in crumpled heaps on the floor, sobbing quietly to themselves as they tried desperately to come to terms with the fact that their beloved iPhones were far less usable than they had been just a few minutes prior. Well, we don't know yet if beta 3 is any better, but it's here -- and if you're a member of Apple's iPhone dev program, it's ready for you to install. So yeah -- take care, good luck, godspeed, be prepared for the worst, and hope for the best. Let us know how it goes in comments, yeah?

Update: And... it's been pulled. Good thing we just restored our phone. We'll let you know if and when it comes back.

Update 2:
Turns out you can still access the firmware with a little creative URL hackery -- but you've still got to be an iPhone dev program member, naturally. Thanks, Brian!

Update 3: Reports are coming in that it's back and available without any trickery!
