The servers at Apple are still warm from the onslaught of iOS 4.2.1 downloads and already iOS 4.3 rumors are heating up. According to a Macnn source, Apple is hard at work at a quick 4.2.1 follow-up with iOS 4.3. While the number jump may signal a rather significant upgrade in features, early rumors suggest otherwise. Instead, the biggest addition to iOS 4.3 will supposedly be in-app subscriptions — a major feature that news organizations and magazine publishers have been pursuing for quite a while.

The release, according to the source, is looking to likely drop between December 9th and 13th. The 9th is important already because that is the day in which Apple and News Corp are supposed to announce “The Daily”, a special, just-for-tablets digital magazine. Having a new version of iOS that can make use of in-app subscriptions coinciding with a major digital publication announcement would certainly please news organizations, publishers, and end users alike.

Early to mid-December certainly sounds a bit too soon for another major update so close to the last. Though as we mentioned earlier, in-app subscriptions on their own are hardly cause for that much hype. But Apple has surprised us before with such things. What does everyone out there think? Could Apple push out another rather major update so close to their last one, and especially focusing so much on one feature?
