For t-mobile USA, their HSPA+ network (or 4G you called) use AWS band, which refers to 1700/2100. The international version N7100 is UMTS/HSPA 800/850/1900/2100. This N7100 is missing the t-mobile USA magic number 1700. So you will not get their HSPA+ speed.
However, with recent t-mobile project on refarming their PCS1900 frequency in the US, the N7100 will work on HSPA+ network, BUT not at current moment in all states. Only specific cities such as Las Vegas, NV will work.
T-mobile USA promised the PCS1900 band will fully operate by end of 2012, so i would say NO for now, but yes in year 2013.
It will depend on how long you would like to wait but t-mobile does have galaxy note 2 (model SGH-T889) which might start selling on October 24, 2012.
Side Note - October 24, 2012 is a big day for US people who want galaxy note 2 as this is the day Samsung Mobile Electronics USA makes for the US Launch events in New York City for Samsung Galaxy Note 2 for all 5 US major wireless carriers.
