That's exactly what I did to save my 6.0.1 blobs on my new iPad4. I haven't gone back to check if Tiny Umbrella has been updated to fix this yet. Once I had my blobs for 6.0.1 I quit worrying. He'll apparently have to come out with a new version when IOS gets updated to 6.1 anyway. As far as I know you are as good as you can get at the current time.
