I really need to downgrade my iPod touch 2g to 4.0. I'm having tons of problems that I can't fix and was wondering if anyone could help. First off, i have shsh blobs saved but all tutorials that say to change the "hosts" file in the folder "ect", my computer says that that folder doesn't exist. Also the tinyumbrella method is not an option because I am running Mac OSX tiger (10.4) and tinyumbrella requires snow leopard. And also because I am running tiger, I can't use iTunes 10. I'm assuming I can't find this "hosts" file because I don't have iTunes 10, but I could use some clarification. Thanks a bunch!
