I have the V505 and I'll be the first to pitch a couple of bitches about it. I do not like the phone book software as compared to my Sony-Ericsson T616. Specifically, the voice dial on the S-E allows you to use just one voice tag with each entry. If that entry has seperate numbers for office, cellphone, or home, you don't have to create a seperate voice tag for each. For example, if I have "Ian" in my S-E, all I say is "Ian". It will beep a second time and I would say "home" or "cell", etc. The V505 requires you to create a seperate voice tag like "Ian home" and "Ian cell". I just think that's a PITA. Also, the cool MP3 ringtones are disabled when you're using a BT headset. To me, that sucks. When my BT headset is connected, which is usually, I don't hear my phone ring "Baby Got Back" in MP3. Strangely, when I use the Motorola BT headset with it the volume is very low. When I use my Jabra BT heaset with it, the volume is great. The Moto BT headset with my S-E is great too. Finally, I like the software on the Moto V710 much better because it has digit dialing and you do not have to program voice tags. The phone recognizes them all.

over.
