Can developer downgrade to older iOS?

[lewy]

Is developer allowed to downgrade to older iOS? For example, iOS 4.1?

(iPhone 4)

Not without SHSH blobs.

Why would you want to?

And now with no shsh blobs on iOS 5... hope there is a solution.

iOS 5 still has SHSH blobs. But they can't be reused like on iOS 3 and 4, yet.

Of course it still has have them, but they are pointless on iOS 5.x as they can't be used to restore and they change on every restore.

There will need to be another method that is used to get around this.

I am already on 5.0.2. If Apple released it publicly tomorrow and ceased signing 5.0 I would not be able to go back.
