    Default No Service with any sim. Jailbreaked and unlocked with Redsn0w alredy.

    Hey everyone, I have a 2g iphone and I've been at this for 2-3 days redoing the whole jailbreaking and unlocking process. I have received no errors during the installation process of jailbreaking and unlocking with redsn0w, but No service message is displayed on the top left corner. I've using Itunes 8.2.0 and firmware iPhone1,1_3.0_7A341_Restore as suggested by iclarified. Every method I tried below was done with a new restore of firmware and jailbreaking/unlocking with redsn0w.

    I've followed this method iClarified - iPhone - How to Unlock/Jailbreak Your iPhone 2G on OS 3.0.x Using RedSn0w (Windows) countless times and the result is the same with No service, but Wi-fi works. I also tried swapping T-mobile sim cards (freshly new ones and old)and its still showing the No Service message. I tried AT&T sim cards (new and old also) and it shows the same message.

    I'ved also tried restoring, jailbreaking with redsn0w while unchecking the "unlock" option and checking the "install cydia", going through cydia using wi-fi connection, downloading Bootneuter 2.1, and installing and reflashing successfully with "neuter" and "unlock" options on for 3.9 and 4.6(with Settings>General>Auto-lock>Never at all times). The No Service message still showed. I also removed/reinstalled/redownloaded Bootneuter 2.1 as suggested by others and reflashed, but the same No Service message is still there. I tried with the fake blank option on (after freshly re-jailbreaking/unlocking)and reflashed but it still didn't change anything.

    I've tried using ultrasn0w after following iclarified tutorial on the above link( and I know it was for the 3G models) but some posts suggest it worked for them but No Service is still there.

    I've tried different methods of using Bootneuter to flash, as in Turning on/off Airplane mode (after it rebooted and shut off CommCenter) and its still the same.

    I've read about being able to downgrade from 3.0 to 2.2 or 2.0 by using an older version of Itunes like Itunes 7.7 or 7.5 associated with the approriate firmware version from other users posts. I've tried it, gotten into DFU mode, used iTunes to detect phone, Shift and click restore, and located the approriate firmware versions like iPhone1,1_2.0_5A347_Restore , iPhone1,1_2.2.1_5H11_Restore. Trying with either version of Itunes, I get an error of 20(for 2.0) and 1403(2.2). Someone suggested 1403 is a corrupted firmware, but if i open with a zip file, it extracts fine without any errors. I re-downloaded the firmware several times and I still receive the same errors while trying to restore. All files have been downloaded from firefox as an ipsw format,not in zip format.

    I've used about 3 different computers and 2 separate usb cables for the iphone and its the same conclusion. All computers have Windows XP Sp2 with Microsoft .net 2.0 already. (Sorry don't have a mac computer to test it)

    Because I couldn't downgrade the firmware version from 3.0, I am unable to try any other program like pwnage tool, winpwn, or quickpwn.

    Is there any way to fix the No Service problem, because I think I've tried every method possible with the 3.0 firmware version with redsn0w and methods to try to downgrade from 3.0 to 2.2 or 2.0 firmwares (but errors occur).

    I am completely stumped. Please help if theres anyone with a different method/idea I haven't yet tried.

    If anyone needs any info about the iphone. Its a

    2G iphone 8gb
    Version: 3.0(7A341)
    Carrier: AT&T 4.0
    Model: MA712LL
    Modem Firmware: 04.05.04_G

    I also came accross this problem and I think because it was not activated so I use Pwange 3.0 instead. I jailbreak & click on activate and use ultrasnow for unlocking, It worked for me.
