How to Upgrade 3g Jailbreak iPhone 2.2 to 3.0 firmware?

How to upgrade a iPhone 3G 3.0 to 3.1.2 (Jailbreak)?

  • I attempted to use Blackra1n to jailbreak it because I read that it jailbreaks all versions. I went through the process, the lady with the 3 iphones came on the screen and then turned off. Now it wont turn back on. It shows the Apple symbol for 30 seconds then shuts off. Im not worried because worse comes to worse I can restore it and update it to 3.1.3 but I rather get it to 3.1.2 because I need to unlock it aswell. Any help would be nice Thanks PS I already attempted the shift + restore and chose iPhone 3G 3.1.2 software and it said it was not valid.

  • Answer:

    Try Blackra1n It worked for me.
