I've been planning on getting the Note. Until now, you had 2 options: buy the slower i717 variant and flash the radio or use the GT-N7000 and suffer using edge only speeds.
After chatting with 2 agents and calling t-mo directly, they confirmed that 1900mhz base band for data should be active everywhere (forums state otherwise), so the international version should get data on T-Mo now.
Has anyone tried? I'm "this" close to picking up an N7000.
