Jailbreak -> 4.0

[Steve Doherty]

I've got a JB 3.1.3 3G. When 4.0 comes out, will updating to 4.0 reverse the jailbreak, or do I have to do a full iphone restore back to 3.1.3 before I apply the firmware upgrade?

Cheers,
Steve

Didnt Know You Could Jailbreak 3.1.3? But I Am Just A Newbie...lol

Similar question.... except I'm a j.b. 3.1.2 3Gs. How best to go about upgrading to 4.0? Should I upgrade to 3.1.3 re-j.b. with Spirit, then when 4.0 comes out re-jailbreak? Will all of my Cydia apps remain on my phone, or will I need to do a full restore?

Yes I'd like to know the answer to this too...is it easy to move up to 4.0?

All you have to do is "Update" to 4.0 through iTunes when it comes out. No need to restore or anything. iTunes will do everything.

You will lose your JB and all of the Cydia Apps. At least until the 4.0 JB is out.
