Sounds like the playing field was evened once the interconnect fees were standardized. It's a shame that we are so far behind in the U.S., at a very fundamental level. Most networks here (particularly the two largest -- AT&T + Verizon) are totally incompatible.

One thing in the US that would never fly in Jamaica is being charged for incoming calls. C&W used to do that when they were the monopoly, but Digicel didn't it. If any of them tried it now, there would be riots in the streets.
Most Jamaicans are on PAYG (or prepaid) plans. As a result, we usually pay full price for phones, whereas you guys can get a high-end smartphone for $200 on a 2 year contract.
It turns out that my sister was actually at the launch of The Galaxy S3 last night! She came back ooh-ing and ahh-ing...
