Version 1.6 of Web King Presenter was just approved by Apple and should start showing up in the App store.
I expect that the free version will be approved shortly as well.
This version has substantial under the hood changes, but does not include any additional functionality at this time. (Although there are new features in the works that this sets the stage for – more on that later).
The changes in this version are to provide support for both the iPhone 5, as well as iOS 6. The minimum iOS supported is now 5.1.
