Running official 2.2.1 myself. Honestly I'd recommend paying xda-developers a visit and flashing a rom and kernel that support voodoo sound(simply amazing AQ for a phone).
Remember to flash the new kernel before rebooting:
Odin 1.7 + PIT files
You're really missing out on what this phone has to offer by sticking to only official updates!
