Hi forum, I apologize for my bad English, i am italian.
My questions are:
1- if i insert one sim in Sony Xperia M dual, in the phone part (where I insert the numbers to call someone) are there two cornets (green buttons)?
2- the update to 4.3 is the same of normal Xperia M?
Thank you very much to all, and sorry again for my bad English! 
no one can answer that question?
When there is only one SIM card inside, you only have one cornet.
Update for Xperia M and M-dual are diffrent. You have top wait for the dual upgrade, but it is promised.
thanks for your reply! regard to the cornet I am happy, but I am sorry for the update! When exactly will it arrive?
I apologize again for my bad English, bye!!
