iPhone developer agreement hints at new version of iPhone OS

An unintended update to the iPhone Developer Program License Agreement went live Tuesday with a placeholder referencing a Jan. 27 launch, suggesting an updated iPhone OS could be presented at Apple's product unveiling Wednesday.

The placeholder can be found on the signup for for Apple's iPhone Developer Program and reads: "Need to update this for the 27th launch."

With Apple's Jan. 27th event drawing ever closer, this placeholder suggests that an updated iPhone OS may be presented along side the "confirmed" tablet.

According to McGraw-Hill CEO Terry McGraw, Apple's tablet device will run a variant of the iPhone mobile operating system, which lends credence to the idea of an updated iPhone OS announcement Wednesday.

On Monday, analytics firm Flurry released statistics that possible tablet prototypes were being used on Apple's campus running iPhone OS 3.2, an unreleased version of Apple mobile operating system. This means that rumors of the tablet running iPhone OS 4.0 could be off base.
