Would it not be made possible to connect the phone to a computer (Bluetooth or USB) and use the computer's internet connection to sync? Surely that isn't too hard to implement? I love Spotify and use it mostly to listen to music in my car. But without access to a wifi it's way too expensive to sync, say, 8 hours of music. And surely that is the whole point of having Spotify on a mobile? Sync options is still the weak point of spotify..
