Samsung SGH-P777
p777 manual link here
1. No bluetooth
2. No speakerphone
3. Unlike the d500, the mp3 player has a true equalizer with presets
4. Unlike the d500, the mp3 player can play in the background
5. The menu has 3 different visual options, much like the p735
I could be wrong on the speakerphone, but I found no mention of it as of yet in that manual
