Today I logged into my PSN account, and realized I had a new message. I checked it and the subject was "Happy Birthday PS3" or something like that, from a user I don't know. I opened it to search for more info, but there was no message, only the subject. I deleted it inmediatly, but later I realized that the net is working really slow, (for axample, it takes a lot of time to enter the playstation store) so now i'm a little paranoid!..hahah..does anyone knows if it is possible that someone hacked into my account only by me opening a message?? I'm relatively new to the PSN so I don't know if this is possible or not. Any help you can give me will be really appreciated!! Thanks!!
