There seems to be a little confusion here regarding 2G, 3G and next G.
The Boost website indicates you need a dual hand set and that one band is 850mhz, this is definetly Telstra's next G network. Why would Telstra give access to this network, because it now has 4G as its premium service.
The dual band handset can use either 3G or Next G in the cities if its available.
Regarding range of the cells (850mhz) in the cities the number of cells and their siting is largely determined by the
geography and the call handling capacity required.
The range of each cell is again determined by the
geography, it could be as low as a few hundred meters, ie in a car park upto 150Kms or more.
In the country the handset switches to 850mhz (next G) for longer range or can still use 3G in the towns. The next G equipment due to the frequency and type of modulation used, the height of the towers and antennas can give much greater range than the 3G. They also use linear amplifiers in most country sites of around 130W from memory, whereas in the metro the output power is around 40W.
The 130W can give a slight improvement in range but is not the main reason it is used, cell technology does not act the same as normal radio, due to the way the modulation works increasing power allows the cell base station to handle more traffic ie calls and does not give a much greater range.
With the use of the 850mhz system, high towers and high gain direction antennas ranges of upto 300km are possible under ideal conditions.
Hope this clears up some of the confusion.
