I'm having problems login to PSN on the PS3, and can't seem to login to my PSN online account at home as well (at home using Symphonet broadband) - was able to download the new update and was able to login to PSN at home 4 months ago with no issue.

However no problem login to my online PSN account at work (work using UNIFI).

Anyone having the same problem? or anyone have any idea if this is a ISP issue or an update issue?
