Jailbroken w/AT&T, not working in China with ultrasn0w

[k2dragon]

My iPhone is with AT&T. Its jailbroken. I am visiting China and I want to use China Mobile. After installing ultrasn0w, it does not let me connect. It says invalid SIM. What can be done? I have 04.26.08. and 3.0.1.

Then maybe your unlock is not working properly. Maybe try install ultrasn0w again.

Keep us posted. I recently used my ATT 3G in China on China Mobile and it worked fine for both voice and data.

What did you do to get it working? Since my phone is jailbroken, I went into Cydia and downloaded ultrasn0w. Restarted and it didn't work. And can you please tell me what other phone companies work in China?
Thanks
