Since the iPhone 4 uses pentaband, does that mean that T-Mobile 3G will also work on it?
T-Mobile 3G is 1700MHz, not included on the iPhone.
It's quad-band, not pentaband.
Yea the "extra" band is 800, which is used in Japan by NTT Docomo.
According to the released FCC documents, it's actually a pentaband chip. Apple might never have any plans to use the extra band so therefore just call it a "quad-band" for simplicity standpoint.
Where did you hear that? The official specs, including the Japanese ones, don't mention 800.
Edit: Acknowledging your edit.
It's listed on the FCC documents: http://www.engadget.com/2010/06/07/iphone-4-hits-fcc-becomes-worlds-second-announced-pentaband-3g/
Read http://en.wikipedia.org/wiki/UMTS_frequency_bands for reference on what UMTS I/II etc mean.
