US STL100-3 Question: How to identify whether the Z10 LE model is RFK121LW or RFF91LW?

I received a Z10 LE (STL100-3) and I am planning to switch to T-Mobile (USA). I understand that there are two models within STL100-3, i.e RFK121LW and RFF91LW (based on the safety manual). Based on what I am reading, T-mobile HSPA+ network may not be supported by one of these models in some regions.

 

My question is how do I find out which model do I have? The Settings --> About  page only shows STL100-3. The stickers on the box and under-the-battery do not have the model number or FCC number.

Please use plain text.
