243w ago - With the release of PS3 Firmware 3.21, many are now planning to hold off updating their PlayStation 3 consoles and use one of the PS3 Proxy applications to bypass the required PS3 Firmware update to connect to PSN.
While most of the applications, guides and videos are quite dated (from 2007-2009), below are links to some to make navigating easier. Special THANKS to ekrboi and themiker for making recent guides as well, also available below.
We will continue to add relevant links as they are dug up, and also links to posts with all new guides that prove useful.

Unless I'm mistaken, since you have 3.10 the OtherOS capabilities have been removed from your system, which in turn means that there really is no point in you holding back from just updating (other than privacy concerns I guess...) So why wait in my opinion... BUT don't take me up on it until someone else verifies that I'm correct or not.
