So upgraded to 3.1.2 and lost any wifi connection even when resetting all network settings. I tried several times to jailbreak with blackrain and still no wifi. Can someone help me out on how to unlock my iphone 3g on 3.1.2 with no wifi. I've been looking online and i don't see anything for window users. I need to know how can i unlock tthis phone with no wifi or cydia, If there is another advice on how i can get wifi back that would be great, or if i can someone downgrade as well would also help, links, steps anything at all would really help out, thanks. One more thing is there a pwanage 3.1.4 out for window users all i see is for macs, how can i create a custom ipsw without pwnage?
