Gonna sell and unlock iphone 3g. Once I install yellowsn0w, can I still use AT&T Sim?

    I will be selling my iphone 3g this week and I want to unlock it. Can I run yellowsnow now and keep using my iphone with my ATT sim, or if I run yellowsnow now, do I have to use a third party sim?

    You can run the iPhone SIM just fine with yellowsn0w enabled.

    Yes, I've unlocked mine while waiting for it to sell and I'm on AT&T.

    You better sell it quick, because the modem firmware for OS 3.0 has already been unlocked by Dev-Team...
