This is a discussion thread for the "TinyUmbrella Updated for iOS 6.1 Compatibility" story posted on the front page.
He's rewriting the next version to have features like auto-update, but this version isn't that. He didn't think he could have the rewrite up in time for a potential jailbreak for iOS 6.1
Save it, just in case. All you need to do is spend a couple minutes pressing a few buttons, and voila!
Any particular reason, outside of being able to save them locally, that this program is any better than letting Cydia save them? I just let Redsnow pull SHSH blobs from Cydia and off I go.
Hmm... I guess if I notice that Cydia doesn't pull them I can grab TinyUmbrella. I haven't ran into a situation of needing them local, but I guess it wouldn't hurt to pull them and keep a copy on my server just in case.
