For those interested, the iPhone has a Test Mode which displays relevant signal information by calling 3001#12345# .
Usually the phone starts with Band 13 and then switches to Band 4 or Band 2.
I do wish that Apple sold the phone using the full feature set of the Qualcomm X12 MDM 9645 modem. Especially places with high population density and very large building that block signal it would be nice to have better signal that the use of 4x4 MIMO 256 QAM would provide.
