"Today, we confirmed that the leaked early builds of Gingerbread (Android 2.3.3) for the Motorola Atrix 4G will, in fact, allow users to unlock their bootloaders using the traditional command: “fastboot oem unlock.” Once users receive the over-the-air update in July, they’ll be able to boot their Atrix 4G into Fastboot mode and unlock from there."
終於等到~!
