I'm UK Orange user it was working fine with 0.9.6 upgraded to 0.9.7 with existing firmware not the (latest update) and now I get "SIM Failure" "Invalid SIM" every time. Can anyone give me an easy idiot’s guide to roll back or how to reinstall 0.9.6 please...? Thanks Fri, 30 Jan 2009 17:47:27 +0000 http://blog.iphone-dev.org/post/74278878#IDComment14490613
