I went through 2 Droid Razrs and 2 Droid Razr Maxx's. Im on my 5th Droid Razr Maxx now. Everything is fine. 3 out of the 5 had the connectivity issues. I got all these within a 3 week span. You gotta know how to call back and complain to get replacements the right way. I was able to test some of them side by side and seen the difference right before my eyes. I believe thats hardware, not software. I had one that worked fine and the other next to it, I would pop my sim back in that one and it would drop data like crazy.
