It's primary limitation is that it doesn't want to tether (at all), which you're not supposed to do anyway.
Oh you can do it - Barnacle works, but you have to tolerate ad-hoc network setup and changing the MTU on your end, or use PDANet. Both are fine, but neither is as nice or simple as clicking "wireless hotspot."
modify prl and build prop and i got 50.0kb/s - 140.0kb/s

according to what I've read, it may only work on the 1800 MHz CDMA bands in the US.
This is hilarious - and wrong.
No carrier allows you to roam on other carrier's towers when you're within range of their towers. None. Ever. They also won't even permit an attempt to force service onto the other guy's towers unless you're in an area considered "fringe" and might otherwise have nothing. If your phone's firmware allows you to do that you can try it with a contract phone and you'll see that I'm right. If you have T-Mobile service for example in many areas you can roam on AT&T. But those areas are places where T-Mobile has no service at all. Try it in a place where T-Mobile has service and you will find that your attempt to register on AT&T's tower is rejected. And yes, all the carriers maintain maps of each other's tower locations and where they have service and they will deny a roaming registration if they have service in that area no matter how crappy it is. The same holds true for Verizon and Sprint.
The reason for this is quite simple - the netting the carriers do means they pay for off-network use.
There are exceptions. After hurricanes around here the carriers will typically remove all blocks and allow all roaming, compensated or not. That's very common after major storms, but it's an anomaly and is due to the fact that some towers may be out of service but the carriers determine that the life-safety value of permitting this use is more important than the revenue (never mind that 911 calls go through whether you have a valid "registration" on a network or not)
So if you go in a place where there's no "X" service, and your phone can roam on carrier "Y" and "X" will permit it on your service plan, that's good. You get service.
But if "X" and "Y" have service where you are, and you have a phone from "X", your phone will always connect to "X" if it is available, and if you try to force a connection to "Y" it will be refused.
This isn't rocket science - it's economics for the carrier involved.
So if you're unhappy with Virgin, but Sprint has towers where you want to use the phone (that is, you have a signal but the quality of service bites) it will bite whether you're on Sprint or Virgin.
That's just how it works.
I wouldn't know, the 2 almost 3 months that I had AT&T, I had virtually no 3G and the couple calls that I did make dropped. Oh and SMS, 2-3 days late. Not bad for $80+ a month.I get always at least 1.5, and usually 2-3 mbs on ATT. Frequently on up to about 3-3.5 mb/s. On 3g (I dont have a 4G phone just a Captivate).
That's some blazing fast 3g.
VM doesn't even have access to all Sprints towers.
I don't believe that is true- you have a source for that piece of info? AFAIK VM has access to all sprint owned towers, but of course it doesn't have access to any roaming towers.
So a sprint phone with roaming turned off should get virtually the same service as a VM phone.
