I updated to iOS 4.2GM yesterday and everything works great as far as I can tell. And I really like it - multitasking, folders, even the changed mute button. Absolutely no problems with WiFi, like has happened with some, and 3G works fine.
I had my iPad jailbroken since the day the jailbreak first came out, I don't yet know if I'm going to miss it for sure or not, but I suspect I will sooner or later. Has anyone had success with using the latest redsn0w to jailbreak an iPad running 4.2GM?
I know that Cydia isn't ready for it yet but I'm guessing it will be in a few days, and yes - I know that the devs will have to update all their apps for 4.2, and I can wait.. I'm just curious.
