Everyone is curious whether iPhone will be for GSM environment or CDMA or for more advanced 3G network. I think it will be now for GSM and later in CDMA also for countries where CDMA is popular.
I wouldn't count on T-Mo getting it any time soon. AT&T has said many times that it has a multi-year exclusive agreement with Apple. At best that means that T-Mo won't get it for at least 2 years.Now that we know it will be GSM since it's coming from At&T, it will indeed be interesting to see just how long it stays exclusive to At&T.
Hopefully the demand will be so strong that the also let T-Mobile have it. That way it will be a lot easier for those already with T-Mo to obtain an iPhone without have to switch carriers.
The cost of moving from one carrier to the next can be quite high with the ETF (early termination fee) fees and all.
Time will tell.
You are so right, as now that you've mentioned it, I do remember that the AT&T exclusive is for two years, with an option to renew.I wouldn't count on T-Mo getting it any time soon.
