Am i eligible for Pwnage tool or not ?

  1. I have an iPhone 3GS 3.0/3.0.1 redsn0wed  : You are in
  2. I have an iPhone 3GS 3.1 and saved SHSH to Cydia : You are in But Downgrade to 3.0 with the following guide Downgrading iPhone 3GS from 3.1 to 3.0 with Cydia SHSH.
  3. I have an iPhone 3GS 3.1 but didn’t saved SHSH to Cydia : You are out of luck

In short the custom firmware is specifically for 3gs users who are using 3.0.X, If you updated to 3.1 without your shsh saved to Cydia then you can’t do anything with this release.

Step One : Download the custom firmware and place to your desktop. These custom firmware are Jailbreaked and  contains Cydia for using the full potential of jailbreaking.

    Hi, for those always on the category of ‘Out of luck’, i.e those got a 3GS with 3.1 out-of-the-box or those forced to upgrade to 3.1 officially by Apple, now at least 2, if not 3 tools will come up by Oct 12. The fastest one probably will be announced in 2 days ! so have your finger crossed.

    To do this do you use iTunes newest version? Or do you use the old version? Thx

    Is it even technically possible to wait for jailbreak for iPhone 3GS with OS 3.1 on delivery? I mean if it’s not even possible to bypass the security on new iphones with factory upgraded OS 3.1, i think i’ll choose 3G..?

    hi Vinay

    in your above post, you’ve said 3GS with 3.1` is now jailbreakable, but only on MAC. if i can have it broken on MAC, after that, can i use to synchronise with iTunes on a windows PC? Please advise.

    • Vinay October 3, 2009 Reply

      @Pankaj Yes it doesn’t matters your phone was jailbreaked on Windows or Mac. You can sync it on any OS from both.

  26. Emiel October 3, 2009 Reply

    ty for the up-date.

    but i got my i-phone 2 weeks ago with firmware 3.1:(
    so i can’t jailbreak it:S.
    so my question is: can i never jailbreak my i-phone? cause i don’t have cydia on my i-phone.

    or i musst to wait if dev team release a tool for this?

    • Vinay October 3, 2009 Reply

      @Emiel Yes you are right, you can’t jailbreak your iPhone 3GS already on 3.1 with pwnage tool right now.
      @Dexter No you can’t use custom firmware to jailbreak iPhone 3GS already on 3.1 because iBoot of 3.1 doesn’t supports the custom (pwned) firmwares.

    i lost my phone number after the update. is there a way to get it back?
