Now, as reported by Engadget and other sources, a new iOS 4.2 gold master (build 8C134b) was just pushed out to developers. Apparently the update fixes the Wi-Fi problem, which prevented at least some iPad users from establishing or maintaining a connection.
Update: I goofed. Apparently build 8C134b first appeared last Friday, not today. My apologies for positioning this as new information!
When will Apple release iOS 4.2 to the general public? Your guess is as good as mine, but I'm guessing it'll be next week--unless the company decides to wait until after the Thanksgiving holiday.
It's been a painful wait--I need multitasking and folders on my iPad!--but I'm glad Apple caught the bug (and elected to fix it) before releasing the update. Your thoughts?
