I upgraded to IOS 5 on accident and I am trying to downgrade to jailbreak again. I opened tiny umbrella and see that i have the SHSH blobs (4.1, 4.2.1, and 4.2b3) and I am curious what the 4.2b3 is. I was running 4.3.2, but apparently never saved the blob for that. is 4.2b3 the one just before 4.3? Maybe I should just wait for the untethered 5...how soon will that be out? any info on this would be appreciated. I tried downgrading to 4.3.2 using a firmware file that I had and holding Shift in iTunes to select it, but iTunes wouldn't verify it.
