Save your SHSH blobs and update now! I feel a ninja iOS update by apple might be in the works.
Apple won't be happy with all their devices fully jailbroken...
Can you save your blobs even before your iDevice is JB?
Yes, you can use TinyUmberella
If you've used Cydia then it likely Cydia will have your 4.3.3 blobs anyway.
New version of TinyUmberella has been released!

I've always saved my blobs, but needed to have to use them to downgrade. Other than TU telling you the blobs are saved successfully, can you manually check they are saved yourself aswell? As like a fail-safe?
I've also read about iFaith as an alternative, anyone used it? It's windows only I think.
What's a blob and why should I back it up if I plan on jailbreaking? Is it just a backup of my iPad in case apple release a small update to counter it?
Looks like we are going to have to wait a bit longer for the A5 Jailbreak.
pod2g's exploit requires a developer account so it can't be released to the public!

That reads as a major setback![]()
It won't be, it bet an untethered jailbreak will be out before February
