Tweet from T-Mobile Help desk confirms Samsung GALAXY Note is on the way
The problem for T-Mobile customers is that a sequel for the Samsung GALAXY Note is in the works and is expected to launch this October. Rumored specs for the sequel include 5.5-inch WSXGA+ (1680x1050) Super AMOLED display, 8-megapixel camera, 1.5GB RAM, S Beam, S Voice, NFC, and LTE. While it certainly appears that the nation's fourth largest carrier is locked into launching the original Samsung GALAXY Note, there might be a point where offering it wouldn't make sense when another carrier, presumably AT&T, is about to offer the Samsung GALAXY Note II.
form factor of the Samsung Galaxy S III says "phone" more loudly than the form factor of the Samsung GALAXY Note.
If you have you heart set on the phablet, don't worry. The bottom line is that the odds favor that it will appear at T-Mobile. As usual, it is the "when" that is up in the air,
