Sprint update rolling out-
Sprint July 17th, 2013
-HD Voice support (enhanced audio in calls)
-Sprint Music added to the ringtones list.
Updated... The update just rolled out to me as well
-Call quality improvements
-Other minor bugfixes
Weighs in at 237.84 MB though, so I would say that is a little more than minor updates....
Details will be updated as they become available in the first post
