Thanks for all the replies since I started this. I have posted this issue on several forums and gotten enough confirmation that it is surely real. A lot of confusion too with people saying they don't drop calls, which of course has nothing to do with the data signal. I called Moto support and they have accepted this to escalate to engineering, I have a case #. They have actually called me back 3 times for more info. I hope this leads at least to at least an acknowledgement if not a fix. I will post the result. If the M sold several million the first week like the iPhone 4, you would hear about it.
