The multitouch support of the Google Android operating system and T-Mobile G1 have been mentioned in the first rumors, but it has never been officially announced. The reason for the decision is unknown, but it's highly possible that Google didn't want to engage in a long lawsuit for "borrowing" Apple's patented solution. The video below is a clear proof that using multitouch is supported both by the hardware and the software, so with the proper tricks this hidden feature of T-Mobile G1 can be activated, although it's not that simple as we need to access the phone's file system with administrator privileges. According to the demo Android'd browser has full multitouch support, which means that zooming and rotating are just as easy to use than on Apple's phone. It is not yet known if the hidden feature will be ever used officially.
