Apple is already at work on an iOS 4.3 update, which should appear in December, a source claims. The focus of the firmware is expected to be on in-app subscriptions, addressing a long-standing complaint with newspapers and magazines wanting to sell iPad content without charging on per-issue basis. In particular, v4.3 may come shortly after a December 9th announcement of The Daily, a tablet-exclusive publication created by Fox and Wall Street Journal owner News Corp.
