Not a true tri-band phone!
However, the three bands -- 850, 1800, 1900 -- offered on this phone are only for the U.S. Region (and maybe a few countries in Europe with the 1900 band). Even on the T-Mobile website they said it's "Domestic Tri-Band."
What was the reason for this move by Samsung? Will it offer better roaming service in the U.S.? Or are they trying to pass it on as another Tri-Band phone? (P735 was a real tri-band)
