Replacement iPhone activation

Hi everyone!

I received a replacement 1.1.1 iPhone from Apple store (meaning that I had no activation screen, just put in my AT&T sim card), and then downloaded Installer from jailbreakme.com. After that I used Anysim to fully unlock my phone, everything worked perfectly.

I have a small problem though, my phone is fully functional with any sim, iTunes 7.4 still prompts me to activate it, without letting me through to controls and sync.

Which of the activation steps I need to repeat for the iTunes to see my phone as unlocked?

Any help is appreciated, thank you ahead of time.

download idemocracy 2, under jailbreak choose activate
