I tried looking back through the posts but can't find anything useful. I remember reading that Tiny Umbrella wouldn't work for A5 - that blobs could not be saved anymore. But then I read sporadic posts within JB threads about it being possible... Before I jailbreak my 4s, I wanted to find out if it was possible... I'd hate to go through reinstalling all my JB apps, have something crash, and then be forced to restore to 5.1 (or later--- whatever the case may be) Does the newest version of TU work for the 4s?? I can't seem to find anything pertinent when I search.
