I also wonder if the airplane mode issue also isn't somehow related to the Moment's "flakiness" when used in conjunction with an Airave. I have had 4 different Moment's, all of which will enter roaming mode, miss calls, and drop calls within range of my Airave, sometimes even when the Airave is as close as 3 feet away. None of the other Sprint phones in my house have this issue.
At present, my phone has 2 bars, shows a -98dbm (LOUSY) signal rating, and is sitting less than 3 feet from my Airave. It is right next to my girlfriend's LG Lotus which is reporting a -63dbm rating.
What is wrong with the radio/hardware on this phone??? This is sooo frustrating.
