| More

Apple recently released the iPhone 3.0.1 update for iPhone users. This update was released to fix SMS vulnerability in iPhone OS 3.0 and does not fix the iPhone 3GS hole. If you have iPhone with OS 3.0.1 then follow the simple steps below to unlock or jailbreak iPhone 3G/3GS using ultrasn0w 0.9 and redsn0w 0.8 respectively.

 

  • Why redsn0w 0.8 can be used on iPhone OS 3.0.1?

Apple made changes only for the SMS bug, which affects programs that redsn0w does not use.  This is the reason you can re-use redsn0w 0.8 on 3.0.1 even though it was written for 3.0. 

  • Why ultrasn0w 0.9 can be used on iPhone OS 3.0.1?

iPhone OS 3.0.1 doesn’t change the baseband and thus ultrasn0w 0.9 can be used as the soft unlock for iPhone 3GS with OS 3.0.1.
