After the release of iOS 4.2, there are already new rumors that Apple is targeting a December release for their next update, iOS 4.3 for iPhone, iPod touch, and iPad.

According to an anonymous source, MacStories on Tuesday reported that Apple plans to release iOS 4.3 in mid-December:

Here’s what we heard from a reliable source: when Apple didn’t know about the WiFi issues in the GM seed of iOS 4.2, the OS was scheduled to be released weeks before Nov. 22nd. Apple found out about the WiFi issues, released a second GM build and iOS 4.2 came out yesterday. It came out in November, but it should have been out in the first half of November. Anyway, before the WiFi issues were discovered, Apple was already planning to release a new build of iOS 4.x in mid-December. Most specifically, they were planning for an iOS 4.3 release on December 13th, which is a Monday.

The source also points out that the release of iOS 4.3 could be delayed due to unexpected issues that forced the delay of iOS 4.2. Besides app subscriptions, the iOS 4.3 may address initial issues with AirPlay.
