Thread: Upgrade and jailbreak

    Default Upgrade and jailbreak

    I read the .pdf file in the "Are You Jailbreakable?" thread but I'm still a little confused over some things so hopefully you guys are OK with me creating a topic about it.

    I have an iPhone 3GS (jailbroken with blackra1n) running on 3.1.2 firmware and my phone really has became slow lately. My problem is that I have downloaded something from Cydia that tricks the phone to think I am using 3.1.3 firmware (I downloaded it so I could use apps that required 3.1.3) and I'm wondering if this will cause any problems if I want to upgrade my firmware? Maybe it is because the harddrive is almost full, or because of all my photos that I have. Is it possible for me to upgrade to iOS4 firmware? I am aware of that I will lose my data. Also will I be able to re-jailbreak on iOS4? Is it worth upgrading?

    What exactly will I have to do in order to upgrade/jailbreak my device to iOS4? Will I be able to keep some of my data? My contacts for example

    Thanks a lot in advance

    If you don't need an unlock, the you can hit restore to 4.1 and jailbreak with Limera1n or GreenPoison Rc3

    can you just update to 4.0.1/2 with no problems? Assuming you have the shsh's?
