My cydia can't find that ultrasnow.
It's ultrasn0w with a Zero not an O.
Xavier.. I havent tried it out but I think you need to enable WIFI, and be in a WiFi spot, beeing connected and then Cydia will find…. need internet connection… at least I think so

Will this work with ITunes 9.2????
Still not working for me. I have Jb'd have cydia. Installed ultrasn0w. Rebooted. Accepts sim with carrier logo but with no reception all calls fail. Plzzzzzzzzzzz help
If your SIM is bring recognized then it's unlocked. I don't see why
you have a reception problem. Try rebooting or rejailbreaking.
Tryd rebooting. No joy. It's even showing my carrier logo and 3g on any sim I put in!! Just won't allow reception. All calls fail.
Frustrating. Will try re-jb and re-do all steps
I Rebooted and would not recognize the carrier, so I pulled the sim and installed again and it worked!!!! I mean it really worked!!!!!!!!!!! THANK YOU 2 MILLION TIMES!!!@!@!!!!
I know you all are having luck but i wanna make sure that when I follow the steps for my 3g with 3.1.2 and 05.11.07 that after I do the 4.0 OS with the custom restore ipsw that it will re-unlock for me with ultrasnow…
worked like a charm. Thank you. Wish there was something that I could do to return the favor.

I have been getting the exact same msg's.. have you found a solution to your problem yet by any chance..??
try using .org
that's what they've mentioned on twitter even though with me, the .org repo is not working as well.
Worked like a charm on Aug 3rd 2010 with the links provided in this post. Follow them exactly and it works. I got my phone in Japan and needed to use it in the US and was able to get AT&T working just fine. Thank you very much for your invaluable help.
