With iOS 4.2 only a few days old, speculation has already turned to iOS 4.3: specifically, the possibility that we'll see upgraded firmware as soon as mid-December. MacStories is reporting that 4.3 will drop in a few weeks, with bug fixes and an API for app subscriptions to support the new "iPad newspaper" called The Daily.
As we know, iOS 4.2 took longer than Apple had expected: when the WiFi bug in the 4.2 golden master was found, they had to go back to the lab to roll out the 4.2.1 version that was released on Monday. According to MacStories, 4.2 was supposed to be out in the early part of November, preparing the way for 4.3 on all devices that would be able to support billing for apps that you subscribe to, rather than pay for once..
