I have an iPhone 4s with iOS 7.0.4, I cannot down grade to 6.x or 5.x. After I tried the steps suggested, it comes with a message "SIM Not Valid". Anyone suggestion, ot it just doesn't work for 7.0.4? Thanks. Joseph

Hi all! I've just jailbreaked my iphone and now tried to unlock it because I changed carrier... now, it keeps searching for the carrier and I cannot make any calls... any suggestion? I'm a bit "fresh" on this kind of matters. Thanks all

Worked at last. Thanks guys. Downgrading my baseband from 6.15 to 5.13.04 did the trick. I have 3Gs and updated it to 6.1.3. with iTunes, JB with redsnow, install Cydia, Ultrasnow, then p0sixspwn for untethered JB. Found everything OK, except it was still SIM locked. Did the baseband downgrade with Redsnow and right away I could call out. Thanks again.
