Sony has updated their TOS, forcing you to agree to the new TOS if you want to still connect to PSN. The new updates mainly say that Sony has the right to “spy” on what you are doing on your PS3 and have officially banned the use of anything on your PS3
To quote the change of TOS:
You agree that you will not use any unauthorized hardware, including peripherals not sold or licensed by a Sony company such as, by way of example only, non-licensed game enhancement devices, controllers, adaptors and power supply devices (collectively, “Non-Licensed Peripherals”) or software to access or use Sony Online Services or any content or service provided on or through Sony Online Services.
