That workaround helps some, but not others, myself included.
But that's beside the point. The noise cancellation was a "feature" which was advertised with the phone, and we paid for it. Now, we are supposed to give up a feature in order to let Motorola off the hook for their poor engineering/quality control? Not a chance. This is 100 percent Motorola's problem to put right, THEMSELVES AT THEIR EXPENSE; not us having to live with some half-baked workaround which a Motorola bean counter decided was the cheap way out of THEIR problem.
Any Atrix owner with the muffled voice affliction who gets all smiley from solving Motorola's problem for them is nothing but a fool.
The good news is that the heat is still on, over on the Motorola corporate forum for Atrix. Regardless of how Motorola tries to ignore it, this problem isn't going away for their "flag****" phone.
