    I have an unlocked/jailbroken iphone 3gs. How can I safely update the phone? I don't even know what the latest update is on my phone and need to educate myself on this. Thanks!

    Glad you asked before you went to itunes and clicked update.
    No, you cannot just update.
    Your iphone will lock and your sim will not work with it.
    It needs work and a custom JB IPSW to maintain your unlockable baseband and restore in pwned DFU mode. Then you will need to install ultrasnow from cydia to unlock. If any of that is confusing and sounds chinese dont attempt anything unless you know 100% what you're doing and getting yourself into.
    Your iphone is not unlocked forever and you cant just update that easy whenever theres a new iOS version out.

    I'm glad I asked too. I assumed it wouldn't be possible to just update it from itunes. Is it possible to do it myself with the proper instruction, or would you recommend having someone else do it?

    I will link you to a step by step tutorial in a few.
    Hope you can follow it correctly.
    Make sure you understand it and don't mess up or your unlock is gone.

    Follow this bro.

    This tutorial will show you how to create a custom JB 5.0.1 IPSW that doesnt update your baseband.
    You will then restore to that JB ipsw using itunes. Once done restoring to it you can open cydia and install ultrasnow to unlock.
    You might need an official sim in order to activate it cause I dont think redsnow hactivates.
    You can use any old inactive AT&T sim if your iphone is locked to AT&T or borrow someones sim for a minute. Stick it in the phone and then plug it to itunes to activate it.
    Good luck.

    Uh oh, I followed the instructions to save SHSH blobs and got this message:
    Blobs are corrupted
    none of the blobs were verified!

    Is there any hope?

    Try Tiny Umbrella to save shsh. Or iFaith on windows.

    I ended up restoring the phone. Now I am uncertain of what to do next. It says to insert a valid sim card with no pin lock to activate the phone. I am assuming this is to be an at&t sim and I will need to have the phone unlocked and jailbroke again?
