"Wait, didn't the Rezound just get an OTA update to build 4.03.605.1?" is something you may be asking yourself right now. And the answer to that is yes. Yes it did. We assume that build was some sort of soak test, however, as it hasn't actually started rolling out en masse just yet, and Verizon has been completely silent about the whole thing.
But this build is one more. Point one more, to be exact; so... we figure it fixes something. There's no changelog, so it's hard to say exactly what that something may be. Alas, it's one less broken thing, so be happy about that.
