Getting an unlocked iPhone 4/4S to work on T-Mobile 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?
Will the iphone get 4g speeds


No it won't. iPhones, even 4 and 4S, are not 4G devices. The 4 is for the iPhone fourth generation, but they are in reality 3G devices. So you won't get better speed than 3G (for sure).

I'm not sure for the network itself since I'm in Canada and I don't look at US providers very often. From memory T-Mobile has a different (AWS) network than AT&amp;T so that could also affect your connectivity and speed. You better check the phone versus provider specifications (or someone else doing the same as you).
