Mobile phone manufacturers and wireless carriers have been working to create new protection mechanisms to stop attacks against the increasingly complex platforms. But the companies also are fighting a seemingly futile battle against their own customers who are intent on jailbreaking or rooting their phones. The most recent example of this came last week when early buyers of the new HTC G2 Android-based phone sold by T-Mobile found that after making some modifications, the devices would revert to their factory settings after a reboot. Security experts say the feature in the G2 that prevents permanent modifications to the device is not a rootkit, and is a function of the way that the phone s storage works.
