Just FYI guys, I used a 16 GB iPhone 3G last summer with the F90BT and the following happened:
entire album art: pixelated
some albums slightly less blurry but still crappy: yes
tried loading literally one song onto iPhone with high res album art: Yes (still blurry on AVIC)
So, please note though that this was when I was still on the initial firmware the F90BT was released with...I no longer have an iPhone (switched to the BB Tour and love it) but I have upgraded to 3.02 firmware and will try album artwork again with a 5G Nano...I'll update again with my experience...
