Will TMobile Phones Work in Tokyo?

I read that in Japan they use CDMA as opposed to GSM like the rest of the world. Does this mean I won't be able to use my TMobile iPhone? Oh, my iPhone uses a really small SIM card, not sure if I can just buy a SIM off the street and stick it in there like I have done in the past with other phones.

Does anyone here have TMobile? What was your experience? Thinking of renting pocket Wifi from Global Advance Communication. This will give me wifi for my iPhone. I guess maybe I could just Skype if I needed to make a call.

There are different T-Mobile iPhone models, with different specs. iPhone 4 will be roaming only IF it is compatible (which i don't believe it is). 4S and newer are fully compatible. If unlocked, you can use a Japanese SIM, otherwise roaming only.

I don't have an Iphone but I am a TMobile customer - they recently started a new program for international coverage - haven't used in myself but supposedly unlimited data, free texting and calls for 20 cents a minute. Check out their website or a nearby Tmobile store - it sounds pretty good....
