C6903 14.2.A.0.290 vs C6903 14.1.G.2.257

[pointandshoot]

Hi,

What is the difference between these two firmwares?

I bought an xperia z1 and I was wondering if i'll get android 4.3 update in uk since my firmware is C6903 14.1.G.2.257. I've noticed (hope i'm not worng) that those with C6903 14.2.A.0.290 already got 4.3 update.

Thank you.

14.1.G.2.257 = last 4.2.2 update for Z1
14.2.A.0.290 = first 4.3 update for Z1

If you will get 4.3, the bild number will change from 14.1.G.2.257 to 14.2.A.0.290. 
Thank you,
