Re-purchased my UK U Ultra.. A quick Question?

[NightOrchid]

Hi Folks

Ive just replaced my U Ultra, after trying the U11, I just couldnt get away with the 11.. I prefer the bigger screen and speakers of the ultra..

I'm in UK and bought it pre-owned BNIB and Unlocked/Unbranded..

What is the latest Unlocked UK firmware version?.

Thanks all
