Your Sony Entertainment Network account carries over to all PlayStation devices, letting you share purchased content among them. For example, purchasing a game on your PlayStation Vita would also enable you to download and play that game on your PSP, if applicable. If you are selling or giving away your PSP, it's a good idea to deactivate your Sony Entertainment Network account from the device as a security precaution. You can deactivate your account from the PSP directly from the system itself, provided you have a Wi-Fi connection.
