SI number can´t be able to upload to Firmware 4.1.B.0.587

[julenar]

My xperia arc s (LT18i) has the 1254.1160 SI number. My phone is Spanish and in Spain this firmware was just rollout. I connect the phone every day but Pc Companion says that I alredy have the ultimate upload for my phone. I don't know iif the SI number of my phone is spanish, so, i think that i will receive the update in a while. Can someone Who got the same SI number help me ?:smileyconfused:

my suggestion is to backup your current firmware then flash the new firmware and see if it's worth it or not, if it's not or when it's available in your country or SI number, flash the original firmware

you can read about warranty on that link aswell
