    Default Random unknown IMEI + ICCID error

    I've got a bit of an odd one here. I've got a 16GB version of the iPhone 3GS (came with 3.1.3 fw installed and 5.12.01 baseband and is an MC model with new bootrom). I originally jailbroke this phone using Spirit and it was fine for a couple days. Then it suddenly lost the carrier signal, showing a searching and then eventually no service status. Not too long after that, it popped up a message saying that the phone could not make or receive calls and needed to be restored. It then rebooted and came to the activation screen (the one that has the option to slide for emergency calls) and the info button showed IMEI and ICCID numbers were unknown. As a last resort, I did a restore the the latest firmware (4.0.1) which as I understand it would also update my baseband. After the upgrade, it was still stuck at the same activation screen with the same problem (IMEI + ICCID unknown). The only thing that got me past this was using another SIM from the same carrier, which then the phone went into the normal menu and then showed a message saying it was activated. After a short while of trying to use it, the signal dropped off again and it hit the same problem as before. It still does that now (4 days later). The only way to bring it out of the activation screen is to turn it off for about an hour and remove the SIM, which it then activates again, but still has signal problems. When the phone was jailbroken, I took the option to upload the SHSH to saurik's server, but I don't think it ever succeeded, as the last message cydia showed me was that TSS request was pending (never said SHSH on file with cydia). I tried downgrading again (editing hosts file, etc...) and it hits an error. I've done DFU mode recoveries of the current firmware it's on now, and nothing seems to help. I'm wondering if there's anything I can do for it at this point. I have an appointment in 2 days for a visit to an apple store to do an exchange, and hoping to avoid that if possible (worried they may discover it has been jailbroken) and wondering if I have to exchange it, if there's any way for them to be able to tell the phone has been jailbroken previously. Thanks in advance for any help with this.

    Edit: I've found that the issue only seems to occur when 3G and carrier network are trying to be used by the phone. If I leave it in sleep mode, it'll be fine for hours. If I take it out and try to call/text/internet, it doesn't take long to hit the error again.

    AFAIK, there's no way they could tell if the phone has been previously jailbroken. The only way would be if they were constantly checking every iphone over-the-air and making a blacklist, but I don't think (a) they do it and (b) the guy at apple store would check before replacing yours.


    Anyway, you are probably getting a replacement right away, tell us how it goes.

    Well, I mean is will they be able to tell with a physical inspection of the phone when I go into their store? There is no cydia or any other jailbreak apps on the springboard, but is there any other way for them to be able to tell it had been done?

    Sorry if I wasn't clear, IF you restore the phone then No, there is no way.

    I bought a 16GB 3GS MB model offline about a week ago presenting the same symptoms, i found that just doing a hard reboot and reactivating it corrects the issue but its only a temp fix, just exactly as described above.

    what's the prognosis on this?

    I jailbroke it successfully tonight with Comex new tool(very nice!) and it's on 4.0.1 - should I be waiting for an unlock, will this soft break have fixed the issue?(only been an hour or two) are there any tools I should grab through cydia to look deeper into this or is there a known fix?

    Any answers would be very appreciated.

    baseband is 05.13.04

    Just to be clear - you don't use an unlock at all?

    If so this sounds very much like either a baseband bug or a hardware problem.

    Get it replaced under warranty ASAP. Yeah you loose cached SHSH - but new jailbreakme works for 4.0

    I have not unlocked it yet

    The phone just basically appears to be deactivating.
    There is no warranty left on the phone.

    Reflash baseband?

    Reunlock using new tools?

    I'm pretty sure the previous owner had it unlocked by a friend and proceeded to update it to 4.0 by himself. Just a guess.

    Being out of warranty I would love to fix it without having to pay apple

    *BUMP*

    Any suggestions before I go ahead and send this off to apple?

    Really keen to get it working again, sending it off is gonna be expensive and take awhile.

    Missing IMEI +iCCID is a serious hardware problem. Most of the time, this cannot be fixed by restoring firmware. The fix for this is to open up the phone and replace hardware component inside at the chip level. Very few places can do this. Best is to see if Apple can help you out by swapping the device
