An alternative to DNS trick, Hideki has released a very useful application to get back your PS3 to the PlayStation Network regardless of the firmwares you are on, including 3.55 CFW. Let’s hear more from Hideki about this in his readme:
Set on your PS3 a web proxy of (PC IP) port 8080
IE: if the machine you are to be running this proxy on is 192.168.0.12 then put that as the IP and 8080 as the port in the PS3 network configuration for your web proxy.
If 3.56 is still current, just run the app and click start.
If 3.60 or later is now out, change the 3.5600 value in required PS3 version to 3.6000 or similar.
As long as the PS3 is correctly configured and this app is running, you will be signed in.
This is licensed under version 2 of the GNU public licence, see license.txt for details.

Please do not cheat in online games, it makes you a lamer and aggravates Sony.

Possible errors
On PC:
If you get an error about mswinsck.ocx being missing, either run the proxy app as administrator or copy the included .ocx file (in \ocx) to \windows\system32. (or if you prefer, download and install the microsoft VB6 runtimes which include this required file but also a large number of other not required files…)
MS VB6 Runtime KB article link:

On PS3:
Error 8071053D – You are not running the proxy or the IP/Port are wrong.
Update request – You have not setup the proxy on PS3 side or Sony have worked around this workaround
via PSGroove
For now, one issue that a lot of people had encountered is that they cannot log to PSN in the games. Hideki is currently trying to work on this.
Hihi
This does not appear to work in games
I’ll look into it tomorrow, I had to go out so skimped a bit on the testing
As for why it doesn’t work in win7 64 bit I have no idea, try running it as administrator, if that doesn’t work, install the VB6 runtimes or port it to .net, the code is very simple and short (and in /src)
