Hi, Google Android applications on the T-Mobile G1 can spawn a telnetd that gives remote root access to your phone: http://www.android-unleashed.com/2008/11/howto-get-root-on-your-android-g1-and.html This particular method needs user interaction, but a rogue Android app could easily run telnetd automatically. Android apps are not normally granted this sort of permission, and granting root is not supposed to even be possible. -jim
