So reading the specs on Apple's site it looks like there will be a GSM only model and another model that supports CDMA. I'm looking at doing the iPhone update program through Apple for the first time. I'm on T-Mobile so the GSM only model would work for me but I'd rather have the model that supports all networks just to keep my options open. Because I'm going through the program and being on T-Mobile will Apple send me the GSM only version? Curious what has happened in the past.
