I have an iPhone 3G that is currently jailbroken on iOS 3.1.3, however I would like to install the latest (or the latest possible) iOS version.

Since I use ultrasn0w to unlock my phone, I have read on the iPhone Dev Team's site that I should avoid updating to firmware 4.1.

My question is, is the latest firmware that I can update to 4.0.1? And would it be as simple as to download iOS 4.0.1, shift restore the iPhone 3G, then simply go to jailbreakme.com to jailbreak and then install ultrasn0w?

Thanks for your input.

Unfortunately, not that simple I believe. IIRC, 4.x firmware have a soft-SHSH that Apple signs in conjunction with iTunes. You would have needed to get this on file with Cydia so the only firmware you can update to is 4.1. You can use the new redsn0w beta that was released but if you update to 4.1, you loose your unlock.

Bumping is not allowed. :)
 
Ok ... so in other word teh soft-SHSH has been introduced for the 3G in 4.0 and higher .... so if i wanted to update 3.0 to 3.1.3, I could use the method mentioned above right?

Yes, it is that simple. No SHSH problems with the 3G. Don't go to 4.1. FW 4.0.1 is as high as you can go to use jailbreakme. If you go to 4.0.2 you'll have to use different software. You start Redsn0w 0.9.5b5-5 and point it to iOS 4, not iOS 4.0.2 firmware, to proceed with the jailbreak. FWIW after being jailbroken on 4.0.2 and getting some lag issues I downgraded to 3.1.3. I plan on staying there until 4.1 is ready.

See that's what I thought too crawsfire .... now I'm just confused as to who is right. As far as I remember the SHSH files needed to be saved for 3GS and newer phones, I thought the 3G was exempt from this.

Anyone else tried this?
