A quick heads up for those of you rocking the HTC One on AT&T. A software update is available (and has been for a while, actually) that fixes a few things in regards to the Media Link HD, which AT&T gave out to those who preordered HTC's latest and greatest. Specifically, some folks hadn't been able to connect to HTC's high-def streamer because of a software glitch. That glitch has been fixed and is now ready to download. It's a small, 269KB update, takes just a minute or so to do, and basically makes your life seem a little brighter. And fixes the Media Link HD connection.
Update: So the update you see above is the one I pulled down weeks ago via HTC's update mechanism (Settings>About>Software updates) and was recently approved. Today, there's a new 20MB update you get via AT&T's update mechanism (Settings>AT&T software update). AT&T tells us this bigger update contains the new Media Link code -- and presumably something else, but we don't yet know what.
