Tethering settings removed from iPad 4.2 Beta 3

Tethering settings were added to 3G iPads after iOS 4.2 beta 2 for iPad was released. It may mean that Apple was going to add iPhone-like tethering to WiFi + 3G models of the iPad. But in newly realized iPad 4.2 beta 3 was discovered that Apple had removed such settings (see picture, earlier the tethering options were under the ‘Cellular Data’ fields). May be we will see these features in new iOS 4.2 in November or may be it was only mistake, and Apple is not planned for a future iPad software release.
