CDMA mulitplexes between 800MHz and 1.9Ghz, and--regardless of carrier or radio--uses the entire spectrum between the two. Honestly, no matter what you flash, you aren't changing the radio at all: you're chaning the operating parameters the radio uses. What's being altered are the instructions for reception and transmission
in those frequencies.
As a very, very, very,
very basic example (and mind you, this is
not a critique on individual radios, and said only for explanation sake):
Let's say Verizon manufactures their radio software understanding the majority of their users are in heavy coverage areas. Knowing this, they deprioritize battery utilization, because they assume you'll be pulling from the tower anyways. Life is great, plenty of bars, and awesome calls. Until, one day, you end up in an area with
low coverage, and your battery life tanks: you aren't pulling from the tower, and the software is forcing your phone into overtime trying to use and maintain the little signal you're able to acquire.
At the same time, your friend using the same phone has the Telus radio. This radio was developed assuming you'd be in areas of low coverage to begin with, and priority was given to establishing and maintaining signal while balancing the power usage to do so. While his phone might outperform yours now, in areas of excellent coverage it will be effectively wasting power (that yours isn't), and his battery life will suffer accordingly.
Of course there's a lot more to it than that, but very fundamentally--and again, not actually radio specific--that's the point of flashing different radios. To find the one that gives you the performance you want for the area you live.
