I'm currently have a 3gs with newboot ...jailbreaked with spirit at 3.1.3 and unlocked. Suppose Apple releases an updated version that updates baseband and whatnot before comex releases his jailbreak for 4.0. That would leave me and alot of people unable to upgrade to 4.0. Any advise. Can i upgrade to 4.0 so i could backup my shsh and then downgrade back.

Setup Iphone as NEW. Then re-apply Spirit. RE-Download it with IE.

As of right now, you can STAY on the 3.1.3 and then Jailbreak with Spirit, then unlock with Ultrasn0w. (Google the guides for how to do this). Once all that is done, Google how to save your SHSH. This will allow you to downgrade back to 3.1.3 in case you accidently upgraded to 4.0 or for some other reason you need to go back.

I never mentioned Spirit. Plus he said his version is 3.1.2. Does Sprit jailbreak 3.1.2? No .....calm down buddy. Whats your problem?

You can install 3.1.3, then jailbreak with spirit and unlock with ultrasn0w Wed, 23 Jun 2010 17:06:39 +0000 http://blog.iphone-dev.org/post/726179754#IDComment81727838 http://blog.iphone-dev.org/post/726179754#IDComment81558655 redmondpie . com /download-ios-4.0-for-iphone-4-9170229/ Wed, 23 Jun 2010 03:25:34 +0000 http://blog.iphone-dev.org/post/726179754#IDComment81558655 http://blog.iphone-dev.org/post/726179754#IDComment81557004 Spirit will allow you to jailbreak and then unlock with ultrasn0w while on 3.1.3 I'd wait a bit though. Cause you never know what clauses there will be if they release something soon.

Please answer. am i correct in thinking that anything with "MC" in the model number is the new "bootrom" And since we're on 3.1.3 and never jailbroken ..can we upgrade to 4.0, jailbreak and then unlock ?

My model is MB715LL. I am currently jailbroken with spirit on 3.1.3 ...so i guess i can't do anything to get to 4.0?

Restore a fresh 3.1.3, activate with official sim, then run Spirit ..then unlock with ultrasn0w.. In order to restore, you need to have your shsh saved on cydia and have your gs.apple.com pointed to cydia.

You should be able to upgrade and downgrade without a prob once you have your shsh backed up.

You have to get the supported sim ...borrow from a friend or check your local cellphone shop like i did.
