I know exactly how you feel. Saw your last thread, and don't blame you for being all **bleep**. To be really honest, its a waste of time on this forum, but i'll try and help. My PSN wasn't working on my 320gb PS3, I posted on this forum, no replies till now. Then I connected my 120gb PS3 and voila! It worked! Hope this is of help to you. Cheers!
And as for all the useless admins and people around, I hope this teaches you a lesson
