What is the best firmware for w580i?

Anybody please tell me the best firmware for w580i.
THanks

i don't own the w580 but the R8BA024 firmware should be the best

not necessary the best, but it is the latest one :)

R6BC002 is the best.

what's is different between R8BA024 & RBC002

Not much:

Java version is upgraded to a new one and it`s a bit faster.

Nice day

Which one is the latest?

R8BA024 is newest

I want the w580i, R8BA024 firmware, APAC 1 description of language, and CDA102774/102. Anybody please tell me the full name of the firmware which I'm looking for?
