There is the link from verizon. It seems that right now service is limited only to those that have wireless service with verizon already. Although unlimited at $30/month is not bad.

It sounds like it is 1xRTT, which roughly corresponds to GPRS on a GSM network. Neither are generally accepted as being "3G." Many people call this kind of service "2.5G."
The main improvement over current cellular data services is that everyone in a cell shares a slice of bandwidth used for data. Since most data is bursty, this is much more efficient. It should feel, most of the time, like sharing an ISDN line. Of course, you don't control who you share with, so it will be intersting to see how good it is in the real world.
There are lots of ways to screw it up by not having enough bandwidth, to using too little bandwidth for data, to not controlling the number of users that can use data in a cell, etc. But if it is done right, the user expereince should be pretty good.
Real 3G uses two systems: An evolution of the CDMA system VZ and Sprint use called CDMA2000 (I bet they wish they didn't commit to that 2000!) and WCDMA/UMTS which vies with G.SHDSL for Worst. Acronym. Ever. These systems will do about the same thing: share data bandwidth among users in a cell. But they will enable up to a couple megabits shared capacity per cell.
The main advantage of data on cellular is that digital cellular is data ready now. You just have to get the phones to share access to the channels used for data, and built a moderate sized data network behind your radio network, and you have pervasive mobile data coverage. This is a huge advantage over systems like Ricochet, which had to build out networks just for data. By borrowing cellular bandwidth and piggybacking on the same digital radios in the cell sites and handsets, the amount of new stuff that has to be bought before we get really widespread coverage is vastly reduced.
