I've done plenty of searching/reading, but still find things confusing so am looking for some friendly advice. I am running a 32GB iPad 3G, 3.2.1, jailbroken with jailbreakme website. Running from Mac OSX 10.5.8. The only things I really need are iFile to modify a few preference files and backgrounder/circuitous. In general I am happy on 3.2.1 BUT: Some software I need to use has been released that needs 3.2.2 (and will probably soon need 4.2.1). A few days ago, I downloaded Tiny Umbrella, and did the save blobs thing - It saved: iPad 3.2.1 (7B405)-xxxxxxxxxxxxx iPad 3.2.2 (7B500)-xxxxxxxxxxxxx iPad 4.2.1 (8C148)-xxxxxxxxxxxxx iPad 4.2b3 (8C5115c)-xxxxxxxxxxxxx I found this a bit odd, as everything I had read online said that now 4.2.1 is out only 4.2.1+ blobs can be saved. Was this something to do with jailbreaking awhile ago? Anyway: iTunes wants me to update to 4.2.1. How do I: Update to 3.2.2 and jailbreak (do I use GreenPoison app for this?) Will iFile, backgrounder/circuitous, and 3G connection work OK after jailbreak? How do I: Update to 4.2.1 and jailbreak (Should I upgrade with iTunes first, then use redsnow for tethered jailbreak?) Will iFile and 3G connection work OK? If things are not as I need after jailbreak, how would I downgrade back to 3.2.1? Thanks in advance for any help.
