Whether or not some of us rather do it the "XDA way", this is a major development. The manufacturer agreed (with resrictions) to unlock it. I always said, it is my device, I paid for it and I ant full access to it.
Wih a but more pressure and time, I will bet you that som eof the warranty exceptions will disappear.
I have HTC devices, all rooted and running CM7 but I am glad to see this happening. It seems Motorola will do the same, eventually this may be the normal.
Besides, when the install software todo the unlock, they also open a door for rooting the "XDA way".
