Phone:  Service is almost always available (as is with all Verizon phones).  Sound is good, but I've noticed echoing with my new phone (I didn't have this problem with my first Chocolate). 

Music:  I haven't found a way to organize the files any way other than alphabetically, which is disappointing because you can't just set your phone to play through a list.  Every time a song finishes, you have to scroll through and find the next song you want to hear.  The sound isn't bad for playing through the tiny speakers, but if you want to listen through headphones, you need to get an adapter. ...
