HTC Willfully Violates the GPL in T-Mobile's New G2 Android Phone (Freedom to Tinker)

I should be more specific. eMMC defines both temporary and "power-on" write protects -- the temporary can be cleared by sending MMC commands, and the power-on (which is in use here) will stay set until a hard reset.

The G2-root team can't work out how to achieve a hard reset, because the card and controller appear to be being externally powered. The baseband uses a GPIO to reset them during a system upgrade, but that GPIO is purposefully shadowed away from the application processor.
