Bypass 3.21 system update PSN requirement:
http://rvlution.net/forums/viewtopic.php?f=43&t=123Figured I'd at least post this somewhere, since Sony made a pathetic move today (April Fools, yeah right) that affects a large number of PS3 owners; the removal of OtherOS. The 3.21 update apparently does nothing but remove a feature for "security concerns." I didn't even want to install it on my PS3 Slim, so I went and adjusted my server to bypass the update for myself and others.
Basically, this will allow you to use the PSN and play your games online while still having an older PS3 firmware version installed, such as 3.15.
If, eventually, a disc game comes out that requires 3.21, you will be forced to upgrade to play that game; there's nothing you can do about that yet. But in the meantime...
You can go to customize your network settings from XMB, and get to the part about DNS nameservers. Select custom, and enter the following IP as your Primary DNS:
67.202.81.137
And there you go, PSN works.
Traducción rápida de lo importante, hay que cambiar en la configuración de red de la consola el DNS primario y poner 67.202.81.137 y ya te deja conectarte a PSN. También comentan que esto no sirve de nada si en un futuro sale un juego que exija actualizar para funcionar (lógico).
Lo acabo de probar y funciona.
