I am fan of XDA developers and obviously i am running a custom ROM on my SGSII. But now an XDA user has hacked , rooted,flash a custom ROM and radio (T989UKLV1) and that was enough to unlocked the 1700/2100 HSPA+ bands that T-Mobile USA uses.
The Galaxy Note features a 5.3-inch HD Super AMOLED panel up front, with a 1280 x 800 pixel count, a 1.5GHz dual-core Snapdragon processor. That’s a step up in clock speed from the 1.4GHz Exynos processor in the original Note. Now T-Mobile users have the chance to use the Galaxy Note without changing carriers.
