For potential iPhone customers in Montana, there is NO good choice. T-Mobile/AT&T are both roaming on Chinookular One (as i call it). Chinookular One is honestly terrible. They get no service in so many places it is not even funny. Hopefully AT&T sweeps them up soon!
But anyways, as far as the iPhone goes. First of all, the process of getting the iPhone to work on Chinook is far FAR more complicated than Chinookie makes it sound. Jailbreaking has NOTHING to do with unlocking. They are two entirely separate processes, which he/she has done neither of since it was apparently given to some associates pre-unlocked. I've gone through all the processes and hooked it up on Chinook. Until recently, Chinook has been rediculously overpriced for data and so i have not set my data up yet. If you decide to go over to Chinookular One and need help unlocking or jailbreaking your phone or any other ways of hacking your phone, let me know.
As far as the T-Mobile ordeal goes, it used to offer 100% roaming, but has now began cracking down on consistant roamers and cutting them off. Chinookie was wrong in saying it is 80%, that is AT&T's policy.
I'm just glad I'll be moving to LA soon, and can escape sucky Chinookular One.
I am just passing on what the T-Mobile CSR told me, if you have issues with them, then talk to them. As far as bashing the company that I work for, that is uncalled for. I am sorry that you feel that way, but I don't go to your place of business and say how crappy of a company it is.
I have unlocked more iPhones than I care to count, and every one is different, depending on the firmware that is on it.
