Good info, guys. I'm an experienced Android-rooter, and I JB'd my iPad 2, though I'm chillin at 6.0.1 with my iPhone 5.
So I'm SOL with blobs for 6.0.1. When I get home tonight, I'll backup, update to 6.1, then install TinyUmbrella and save my blobs just in case.
What about APTickets? Do I need to save those? If I ever need to downgrade? I thought that's what blobs were for...I'm just trying to get an initial grasp on when I will need each.
