Do you really think IF you change your PSID back they do NOT notice? Your still using an prohibited piece of soft AND hardware to realize this. SO you will be banned anyways.
minddagap: Like you gona get a new one? PSJailbroken PS3s are NOT refunded, switched, repaired or what receive any service of whatsoever from Sony. Plus the shops are allerted for crime! I work at the Intertoys in the Netherlands and people are NOT allowed to switch the PS3 anymore. For warranty they should contact Sony!
