According to whispers around ye ol’ Rumor Mill, today was to be the big day for iOS 4.2 to start hitting iPhones, iPod Touches, and iPads everywhere. As the daylight burned, however, a new rumor popped up: due to WiFi issues on the iPad build, the launch was being pushed back a few days.

Aaaand sure enough, we’re told an ever-so-slightly modified version of iOS 4.2 for iPad has just hit the Developer Center, rockin’ a build number of “8C134b” instead of just “8C134″.

While this doesn’t positively confirm that iPad WiFi issues are the cause of the “delay” (its not really fair to call it that, as Apple didn’t announce a date themselves), the fact that this new Gold Master is solely focused on the iPad and the fact that our iPad has been having one helluva time staying connected to WiFi lately just fit too dang well to think otherwise.

This is, as far as I know, the first time that Apple has modified a Gold Master after sending it out.
