4G connectivity is much better. Since yesterday I have only lost data once and that was in a basement parking garage. Typically I would lose 3-4 times per day.
Also confirmed with someone (at Moto) who knows this is the "currently being tested MR (maintenance release)" so I am stoked the device works now with maps, sky, and a data (mostly). I will fire up the hot spot later this week and see if the https issue is resolved. One day of use is only a couple dollars and it is the least I can do for you providing this fix now.
Update: hotspot feature fixed and seems to work with all the https sites it failed before on my trials. this is indeed a good fix for Razr
Update 2: No 4g/3g data loss since I posted this morning. One annoyance encountered on hot spot usage; when enabling hotspot 3 times today my macbook did not see it one time. I had to disable then enable the hotspot on the device then it was visible to my macbook. The mac saw other hotspots in the building but not the droid so I am sure it was not the mac.
Over all rating: Outstanding. Phone is no longer hobbled.
Update 3: Had a data drop but difference is it recovered on its own in under 20 seconds.
