According to Wired a Federal Magistrate has allowed Sony to access George 'Geohotz' Hotz's PayPal account as part of its civil lawsuit against Hotz. Sony is claiming that Hotz received payment through PayPal for his PS3 hack.
Apparently Sony would rather try the case in San Francisco, as opposed to New Jersey, where Hotz resides. If Sony can use the PayPal history to prove that George Hotz received donations from Northern California, then Sony can convince the courts to try the case in San Francisco.
Hotz is currently claiming that he did not receive any payments for the hack.
This is the latest in a number of attempts by Sony to gain information from George Hotz, after successfully winning subpoena's for data from Youtube, Google and Twitter. Sony were also granted the right to the IP address of anyone who visited his site.
