I'm in a high saturation of 3G/4G area of coverage for AT&T (yes, in the US folks) yet my N9 does the weird robotic voice like it is having a hard time receiving signal or something.

I'm a notorious bluetooth user - with my Pioneer car stereo or with my Bose Series 2 headset; however I think I finally figured out the problem.

I had finally convinced AT&T to give me one of their microcell signal boosters and while I finally have 5 bars all throughout my house, the issue with voice going in and out in that aforementioned robotic manner continued.

Right until I switched away from wi-fi to just 3G access for data. The problems went away for the most part.

Now... what do I do? It seems like wi-fi, bluetooth and whatnot is causing my problem. I didn't have this problem with WP7, iOS or Android.

But on my N9 - both of them - it's a problem if it's (assuming here) switching from wi-fi to 3G for data while using bluetooth. Any help? Anybody else having this problem or seeing this too?
