I am trying to activate my iPhone for use with my supersim. It was working fine. I tried to do the youtube trick. It failed. I restored and now every time I try to activate it all goes well until I get the alert that there is no signal.

I have tried activating via iActivator, iNdependence (on gf's mac), the steps outlined on 'hack the iphone . com' (on my pc) . and each time I think it is about to work until I get the alert regarding signal.

I have the latest firmware 1.0.2 and have itunes and ituneshelper both closed.

I would really appreciate any help I can get regarding this issue.

Thanks in advance, Richard
