Tiny Umbrella Updated With Baseband Protection for iPhone 4

[mikeee]

Sorry to bump this but, does the TSS function apply only to updating software or downgrading as well? An example is : you're on ios 4.1 with ios 4.0.2's 1.59.00 baseband and something happens to your iPhone and you only have the SHSH blobs for 4.1 saved. Thx in advanced guys.

If you're on 4.1 with the 1.59.00 baseband, restoring with 4.1 using Tiny Umbrella will leave your 1.59.00 baseband intact.

Signature hashes from Apple are required to install a new baseband on the iPhone 4 (similarly to the operating system). Since Tiny Umbrella only signs hashes for the operating system, the baseband won't get written to the iPhone 4 during a restore (if using Tiny Umbrella), no matter what version you're restoring to.
