Thread: jailbroken 3g 2.2.1 has no signal/no service

    Default jailbroken 3g 2.2.1 has no signal/no service
    I've searched and got nothing. I upgraded to 2.2.1 and had to jailbreak my phone again. After jailbreaking, phone has no bars then go to no signal moments later. Restore with a fresh non-jailbroken 2.2.1 and I have service again.

    Any ideas?

    Thanks in advance,
    Justin

    I had the same issue. I'm using an aluminum Macbook with the OSX 10.5 cache fix and a two day old iPhone 3g.

    I also upgraded on accident and I was able to downgrade to another .IPSW from earlier but I wasn't able to get signal, so I had to restore to the latest firmware so I can receive signal again.

    I had the same problem.

    Use Pwnage to build a new .IPSW but DON'T choose to activate the phone. Plug into iTunes, and let it register with the network. Works every time. I know...not much use if you're not on AT&T, but it's a start.

    im having a strange problem here... i loaded cpjr's custom .ipsw file (works AWSOME btw), have 50mb free memory, running real lean and clean, but there is one problem... according to SBSettings, i have a data ip address and a wifi addy, if i turn off the wifi (which free's up 5mb btw) and respring, it still shows a data (3G im guessing) ip addy. i cant access the internet through anything, keeps giving me the error not connected to internet. i have 5 bars service and the 3g icon is there, but no dice...

    anyone go through this before and know what to do... any help would be great!!

    i have a 8GB 3G, only 3 days old.
    cpjr's custom .IPSW file
    SBSettings and cydia installed....

    other misc apps that come preloaded

    that's it.
