you're just awesome - I was surprised to see a link to my site. Thanks for the support!
Now if you'll excuse me, I'm off to apply for this guild. :)
Sep 25th 2007 12:51AM Confirmed, if you have 'invalid SIM error', run anySIM. It froze first time, but I restarted the iPhone and ran anySIM again. After that iPhone worked just fine.
Sep 24th 2007 11:51PM 'Incorrect SIM error' as well. iTunes restore doesn't help, nor the new blank SIM card from AT&T. I'll post if I figure out a solution.
