Sorry for newbie question. I'm a bit confused. I just d/l'ed tiny umbrella to save my SHSH blobs. I was under the impression I couldn't save my 4.3.3 blobs, because Apple is currently on 5.0.1. However, if I load Cydia, it says I have 4.3.3, 4.3.4, 4.3.5, and 5.0.1 blobs. I ran Tiny and when I hit save blobs, it appears to have saved all of the versions above. Is this because Cydia saved the blobs for me? Does this mean I can upgrade to 5.0.1 now and later downgrade to 4.3.3 if necessary? Additionally, can I upgrade to 5.0.1 even when Apple stops signing it when/if they release the new iOS? I am on an IPAD2 WIFI only. Thanks for your help and clarification.
