quick question?

Hunter - read a lot before you do this, especially all the detailed instructions on how to unlock, how to flash, and what can go wrong. Anytime you're overwriting the entire ROM on your phone, there are real elements of risk (including bricking the device). Don't go there if you're not willing to take that risk - or potentially spend time debugging problems.

Having said that, MightyROM is really nice, far superior to stock, and as long as you follow all the steps correctly, it's fairly painless - although a bit time consuming. Just read up first, know when you need to hard reset and "clean storage", what cabs you'll need after etc.
