No service/reception after jailbreaking with PwnageTool

So i followed the steps to jailbreak my 3g iphone. I had reception at first (it was activated). I downloaded pwnagetool, ran it and changed the settings so that it wouldn't put any custom logos and that it would erase everything (unticked the 'disable partition wipe-out,' and I think the problem might be here), and restored with with the custom .ipsw file. iPhone works 🙂 But without reception 🙁

So no service. And I put my SIM card in my friend's iPhone and it works just fine.

Please help 🙂 Thanks.

Ah, i think it's because I forgot to uncheck 'activate the phone.' Now what do I do?
Edit: did another pwnage without activation and it's fixed 🙂
