Ok, so I found some time finally to go through the emails that Apple had sent me regarding the OS 3.0 GM seed, but when I tried accessing the link to see the checklist for migrating an app, it kept on redirecting me to the login page...arghhhhhh. This is also happening if I try to access the forums. Will contact Apple support.
Meanwhile I'm downloading the huge OS 3.0 SDK as well (since I'm still on Leopard... the Snow Leopard version is approx 1.5g smaller). I don't have a clue from where to get the GM seed.
