We’ve talked about Notcom releasing an update to TinyUmbrella, a tool to save your iOS 4 SHSH regardless of whether your iDevice is jailbroken. Today he released the updated version of TinyUmbrella, adding support for iOS 4.

(Linux support is there – just buggy – Sorry I’m working on the segfaults posixninja )

I’ve tested this with iTunes > 9. (Up to and including 9.2)

Supported devices:

• iPhone 3GS
• iPod Touch 3G
• iPod Touch 2G
• iPad (No changes as 4.0 hasn’t been released for iPad)

Note: “If you have an iPhone 3G you don’t need to save your SHSH.”

Download:

• Windows
• Mac
• Linux (Buggy)
