Hey all, i have an Iphone 3g. It was running 2.2.1 JB and UL using a Turbo Sim to connect to T-Mobile. My issue started when I was going to upgrade to 3.0. I started the upgrade process with the T-Mobile SIM inside the phone along with the Turbo Sim. After a few minutes, I realized what I was doing and replaced it with an active ATT Sim. Well... after it finished upgrading to 3.0 Itunes prompts me with the error "The SIM card inserted in this Iphone does not appear to be supported". This happens after I have placed the ATT Sim in the phone. I then continued to do an Option+Restore restoring the patched IPSW, iPhone1,2_3.0_7A341_Restore.ipsw and still no luck. I then restored to the factory IPSW with same result on a mac and pc!!! Anyone please help... this is my moms Iphone and I'm pissed at myself for making that stupid mistake. Thanks guys!
