After 2 days of agony, I finally figured out a way to fix the Slow Download problem off the PSN that some people have been reporting. The solution is simple.
On your PS3, set up a new CUSTOM connection. Configure everything as it should be, and when you get to the DNS Server option, put MANUAL and input the following as your Primary and Secondary DNS servers:
Primary DNS: 18.104.22.168 Secondary DNS: 22.214.171.124
Those are Google's DNS servers.
This FIXED my problem almost completely. Went from 5000 minutes left to download patch 1.05, to about 30 minutes total.
I hope this helps anyone still having problems.

This did not solve the problem for me, the speed MAYBE was a little faster, but my other downloads were having trouble and going slow as well and during the connection test the connection speed part failed.
