Congratulations! If you are reading Step 2, that means that you successfully unlocked your phone (or are about to make a no-no). Make sure that your phone is HardSPL unlocked or else you will not be able to flash.
Taste is a matter of personal choice. As I stated in my previous post, most of the development for this phone is being done at PPCGeeks, and since posting every Rom thread in here would be time consuming (and possibly useless), I am giving you this link to all the custom ROMS.
Which one is best you ask? Again, a matter of personal choice. Some roms are feature packed, whereas others are light and fast. Really up to you...
