There are several aspects I'm not clear on, and I'm wondering if what I want is even possible.
1) I want an unlocked (officially; no jail-breaking) iPhone 4/iPhone 4S. The iPhone 4 unlocked is currently $550 for 8GB at Apple. I think they'll be announcing the pricing for the iPhone 4S unlocked sometime in November.
2) I'm only interested in a month-to-month plan from T-Mobile. I see some listed here: T-Mobile Plans The one that looks best to me is the new $30 "Unlimited Web and Text with 100 Minutes Talk". I've noted that only the first 5gb of data are at up to 4G speeds, I guess the rest go back down to 2G. This will be more than enough for me.
Is this possible? Will the iPhone 4 get 4G speeds even though it is not "supposed" to be on the T-Mobile network? If this is possible, how do I go about doing it? It looks like I need a "micro-SIM"? I'm fine with giving up my old cell phone number. Are there any potential issues with trying to get this (i.e. Does t-mobile only give me a micro-SIM with a "qualifying" phone purchase or something? Or do they have to activate the phone "in-store" or something?)
Any potential issues you guys notice?
