I brought a Playstation 3 when it was released and I was under 18, so my older brother took the Master Account. Now that I have turned 18 and my brother is moving out, I now have the PS3 to myself however I am still on a sub account. I have tried changing but can't find any way to do this.
My brother plans to buy a PS3 in the future keeping the same PSN ID.
If it's impossible to change account type then is it possible to give more priviledges to a sub account such as controlling finance, facebook integration etc.
