Droid has been rooted. It was only a matter of time but we do like to celebrate this sort of thing. Why? Because if you pay for it you should own it. This will probably spark a flame war about licensing agreements and such in the comments but answer this: if it breaks, who pays to fix it? If you’re the one paying for it, you should be able to do what you want with it.
The process seems simple. Copy the magic file onto your SD card and go through the firmware upgrade process. Just make sure you know what you’re doing so that you don’t brick this sexy device.
