Hi
I was wondering why the number of updates for the version of dul SIM card is much less than one SIM card
Do not forget our Sony ? 
I also got an update 1
But the single SIM version update has received numerous
I am still waiting for version 5
Hopefully Sony will be better supported by this handset
Because a single SIM version is no different in terms of hardware and ...
It's not about Sony - It's a about whether or not your network or country will authorise the update
