GoPhone on AT&T on iPhone 3G with 3.1 Software??

[marktaylor22]

Is anyone having any luck getting the iPhone activation to pass using a jailbroken custom ipsw for 3.1 for the 3g?

I have no problem getting passed activation on 3.0.1 but when I used the custom 3.1 ipsw I keep getting no service.

Anyone know what to?

Thanks in advance!

You have to go to expert and and uncheck activate and you have to activate in itunes. But since your on 3.1 you cant do it at all. I would just downgrade back to 3.0.1

Thanks for the tip! I found a custom 3.1 3g IPSW that was Unactivated and restored and it worked perfecto.
