Hear, hear! I just signed up for Premium and highly doubt I will let it go beyond 30 days because I can't get it to sync my music. It gets going with a progress bar but then just stalls out for no reason at which point I have to start the process from square one. Tried this a number of times because I'm going on a fishing trip and was hoping to use this feature on the boat, doesn't look like that's going to happen! Garbage.
p.s. I'm still plugging away with an iphone4 but, in my mind, that shouldn't make a difference if it supports the app! Very disappointed.
