So, I got 5.9 about a week ago (that usually means the next version is due imminently...) and slacker has different behavior. While the stuttering appears to be gone, it seems to be replaced with "I give up, next song". I live in an area that has ok AT&T coverage 2 and 3 bars according to the car. Previously, this has lead to stuttering (1-2 second pauses, several in a row was typical). Now, instead of resuming after a few seconds, it just stops playback and, after 3-5 seconds, starts a new song. This happens about every 3rd song. Pretty annoying to be in the middle of a song I like and BAM! next song. Previously, It would give up after a series of stutters. I'm not sure that slacker actually changed but it's behavior sure has. BTW, the service center checked to make sure I had a good connection to the antenna (I did) and could not see anything wrong elsewhere. Anyone else see this?
