Samsung Galaxy Tab 2 (10.1) for T-Mobile visits the FCC5
When the SGH-T779 received its Bluetooh SIG Certification, it linked to another tablet, the SGH-i497 which is the AT&T version of the Samsung Galaxy Tab 2 (10.1). The guys at Unwired View, coming to the conclusion that the SGH-T779 must then be the T-Mobile version of the Samsung Galaxy Tab 2 (10.1), took a picture of the tablet and superimposed it on the FCC diagram. Yes, it was a perfect fit, for what it is worth.
Bottom line, it looks like T-Mobile is getting a solid 4G enabled 10.1 inch tablet to go along with the Samsung GALAXY Tab 7.0 Plus which also supports 4G.
