How can I Update android? Xperia SP?

Question

I would ask about to update my Xperia SP. 

As I have seen in the forums and the Sony website, and there is an upgrade to Android 4.3 since February this year. Elsewhere I've been reading that the availability of the update depends also the operator. 

Anyway, I'm with Orange and not let me upgrade (I've tested both the PC-companion from Sony and from the phone). 

My question is if there is any way to upgrade to Sony official rom if it's worth doing and if lost phone data. 

Thank you very much! 

A greeting,
