There's a little known yet very disappointing fact about the Playstation Network that we're going to share with you today. If you have a friend who lives in a different country, then its possible you will not be able to add them as a friend on your PS3. The reason why is that if you register your PS3 in a specific country, your Playstation Network is limited to that region. I have yet to confirm this for the rest of the world, but it is currently the case in the United States. So, if my friend from the United States registers his/her Playstation 3 while they are on tour in Iraq/Afghanistan, then I will never be able to add them as long as I'm a US resident. This is extremely disappointing, Sony.
