I have been a break for around a week and during this time quite a lot happened. The new firmware totally revamped the security of the PS3 so I would not be expecting a new CFW anytime soon so if you are still at 3.55 I would stay with it (plus 3.60 really doesn't have much improvements that directly effect you), and don't worry because along with the update many may think that PSN access is lost but on the same day that the update came out a useful version spoofer came out.
Team Rebug who has steadily been releasing homebrew for the PS3 devolved a version 3.60 spoofer which allows PSN access and extremely easy access as well. If you though fuckPSN was easy compared to the old methods then you will be shocked by the simplicity of this. All you need to do is install the pkg and run it and hit the X button to install the spoofer. It does take a while to install the spoofer and there is no sign at all when it is done so definitely wait a while so you know its done. When its done just exit the spoofer and sign in that easy.

If you messed up the spoof install and your PS3 stops sending video input to your TV (this happened to me) you have to start your PS3 in recovery mode and your TV will receive input. Next you will have to reflash your PS3 to OFW 3.55 and then back to your preffered CFW. If you do this all your account info will be lost and saved files. If you want to avoid a loss in saved files you need a spare 2.5 inch SATA hard drive. Reflash your PS3 with the spare HD then after you are done put your old HD back in and your files will still be there, but your PSN account info will not but you can just enter that again.
