Apple sneaks in iOS 4.1 via iTunes, This is how you save your iPhone 4, 3GS!

8 September 2010 4 Comments

Apple just released iOS 4.1 update, not a super important update for 3GS users (unless you are into GameCenter!). iPhone 4 users can finally relax given that iOS 4.1 comes packaged with a fix for those nasty sensor issues.

Before you do any thing, please quit iTunes and do the following. TinyUmbrella is what you need to save your iPhone from Apple’s anti-jailbreak updates.

Download TinyUmbrella for your Mac/Windows/Linux.

Install/Launch TinyUmbrella and save SHSH blobs for iOS 4.0.2 for 3GS, iPhone 4 from Apple (or Cydia after the SHSH blob signing period by Apple is up).

Will make a detailed post about actually using the SHSH blobs for downgrading the iOS firmware.
