    Default Downgrading Pwnage 2.2 iphone 3g to 2.1 ??? Pwnage 2.2 Problem

    I have an Iphone 3g that was factory released with 2.1 ... I did a quick pwnage to jailbreak and activate so I could use it with my Gevey. Everything worked fine until I had the greatest idea of the year... Upgrading to 2.2 without upgrading the baseband using a Pwnage and custom file.

    Created a Custom File and Updated as Instructed in the forum. Upgrade went fine and phone worked flawlessly after the update. This was until i got the "NO SIM" error during the night. After that got the infamous "Carrier Update" that won't update. And a Basically useless phone. Because at random time the phone goes "No SIM" without any foreseeable reason... and the only solution is taking the sim out, shutting down the phone, turning the phone on, inserting sim without the gevey, shutting down the phone again, inserting the sim and gevey and turning the phone on with the crossed fingers.

    The questions are the following:
    1- Do you think that if i do a downgrade to 2.1 everything will work fine again??
    2- How the heck I do that??

    Yeah you could try. It would be simple, just use a 2.1 IPSW package and restore thru iTunes. If you DIDN'T update the baseband I wouldn't think that you would be having those issues but who knows. They say that your not supposed to update if your using a sim hardware hack. Like I said if you used a custom IPSW and didn't update the baseband then try downgrading to 2.1 and see what happens. Can't hurt you at this point.

    Below is the link to download the iPhone 3G 2.1/5F136 Firmware direct from Apple.

    Version : 2.1 (5F136)
    Carrier: Carrier 2.6

    I upgraded to 2.2. originally with Pwnage Custom Ipsw... But who knows ??

    Hi there

    I'm new on this. I've a question: how to know which baseband my iphone has.

    I'm pretty sure I have it in front of my eyes but I'm not able to see it.

    Thx!
