T-Mobile threw a screwball like week telling everyone that T-Mobile Galaxy Note 2 will be one of the first 4G LTE phones. That’s just great news for T-Mobile Note 2 users as your phone does indeed have a 4G LTE hardware, you just need to update your latest firmware to 4G LTE supported firmware.
If you want some serious 1.8Ghz quad-core speeds, multi-view, and wifi-calling, there’s finally a ROM for that, MyROM.
Based on latest T889UVALK8 firmware, MyROM brings UI/RAM/Network speed tweaks along with Note2Core kernel (overclocked to 1.8Ghz out of the box, no need to install SetCPU). Pretty simple ROM yet very fast and brings some of the latest multi-view features.
