Obviously, the Samsung forum is not a good place to ask about Sony products. So I'm locking this thread.
You can try our Sony forum http://www.cnet.com/forums/sony/ , but I think our phones forum http://www.cnet.com/forums/phones/ is better suited for your question.
Moreover, there is no need to post your full name in the subject line, or even in the post. Now the world can see that you don't know the difference between Samsung and Sony. That's not what you want, maybe?
