When I first got my phone I loaded some music onto it to hear how good the speakers were. The next time I went to play some music it started trying to load track after track and told me that it couldn't load the track.
I deleted all the music and reloaded it again. Same problem - first they would play and then after a track or two nothing would work. I deleted everything again and loaded a single song. Still the same.
I then bricked the phone trying to update the FW. Now I've got that fixed and with the latest Euro 1 FW it's still doing the same.
My music is on a 16GB card and there is only about 2 GB on it.
Nokia Multi-Media transfer does work partially with the N97, but it tells you that it is not recognized. It will still copy over music files and photos though.
The main pain in the butt is that there is not an i-Sync plug in yet for the N97 so I have to enter any appointments in my mac and N97 separately. hopefully it wont be too long though as I'm close to shutting down my N97 and going back to my N96 until there is another software revision and i-Sync plugin.
