Well, Sprint's A840 has a speakerphone. I would be extremely surprised if Verizon wanted it removed. Likely the only differences will be that the Verizon model lacks AMPS support and a universal charging port. (A670 vs. A680)
I realized I misread the post before mine. I want a full duplex speakerphone. The N330 has a half duplex speakerphone and I know people who have it and if we both speak at the same time, we cancel each other out. So... does this have a full duplex or half duplex speakerphone.
