The aim of the 4.3 release includes iOS

MuscleNerd twitter just published in more news about the release of the iPhone 4.

Confirms that we are working on Ultrasn0w, and that its next version release all basebands including IOS baseband 4.3b3, which we hope will be the same as the final version.

With these data we can almost ensure that the release will come with the jailbreak of iOS 4.3, we expect this soon.
