Very fast startup time. You won’t find any startup wizards in this ROMs. You’ll be up and running in a couple minutes after flashing the ROM and ready to go. No need to spend time to set everything up.
Eye candy (looks great and for it to all flow together nicely)
Smoothness, consistency and good aesthetics
Stability through private beta testing before public release
You need to install a modified “SPL” on your device that allows installation of custom ROMs such as this one. It’s called a “Hard SPL”. If you have a T-Mobile USA branded device, then you don’t need to flash a “radio”. The ROM will work just fine with it. However, if you own an asian or european HD2 then you NEED to flash a .50 radio.
