Not throwing out any particular favorites, just some reading materials-

pretty nice stuff, it'll go over a lot of points you may want to know.
Just from personal experience, the iDen stuff that Nextel runs on, has a
wicked nice data transfer, it has integrity and I think speeds are around
33.6 pretty consistently. I know that Aerial (now voicestream?) used to
guarantee 33.6 and above, but ever since Ricochet went to the ISP
graveyard, I don't know if anyone is saying much more than 33.6 for
consistent speeds.... Anyone?
