HTC G2 is one of a handful of phones that run the Google Android mobile operating system, which is touted as an open platform, often in contrast to Apple s iOS. The new phone also has a hidden capability that is designed to roll back any modifications made to the G2 after a user has jailbroken the device. Security researchers say that the ability to revert to its original factory state is by no means a rootkit and likely doesn’t violate the Apache open-source license that Android uses.
