I have JB'd my iPad, I ran the Firmware Umbrella and I see the Cydia has my SHSH blobs on file.
I think there's a small area that I'm confused about, and that's "updating" the firmware on my iPad.
I've already modified my hosts file to point to sayurks server (sp?), so I'm not terribly concerned about running into any unwanted updates, but I guess my area of confusion is this (Please note this is for the WiFi Version, not the 3G):
1) I see a lot of people talking about the fact that if you do not back up your blobs and you update to a different firmware, you'll NEVER be able to Jailbreak your device again because your blobs don't exist. I don't quite understand that.
2) If I decide I want to upgrade to the new firmware, with my "blobs" on file, but then want to "downgrade", is there a step by step guide as to what to do? How do I access my SHSH blobs on the server? Or the ones I have downloaded to my computer?
I appreciate all the help, and I know a few of these might be stupid questions
