iPhone OS 4.0 Beta will be launched January 27th

French site Mac4Ever (Google translation) claims that Apple's special media event now reportedly scheduled for January 27th will see both the introduction of the company's much-rumored tablet device and the launch of beta versions of iPhone OS 4.0 and the associated Software Development Kit for developers.

Rumors say SDK will include a "simulator" to assist developers in adapting their existing App Store applications to support the tablet's screen resolution. The deployment of tools for supporting multiple screen resolutions could also pave the way for a higher-resolution iPhone in the future.
