I just got a Motorola e815, along with Verizon Wireless's $59/month unlimited data for your laptop.

It works quite nicely on my 770. I've been using it with Maemo Mapper, and it's really nice. On my laptop, I often measure 600 kilobits/s downloads and 60 kilobits/s uploads. They also give you an actual routable IP address that accepts incoming connections.

I don't like the way that Verizon disables features on your phone to make you use their picture messaging service instead of Bluetooth on your phone. I also don't like the way you can't install your own ring tones from your own MIDI files.

However, the data service just works, no hacking required, and it's really fast.
