Hi, i've updated to the 3.0 firmware, jailbreaked it and unlocked it with ultrasn0w. I haven used yellowsn0w before so this is the first time I use the soft-unlock method. Here is the thing. When I try to sync my iPhone 3G with iTunes it tells me that i have a different SIM-card. And yes, I am not using the original carrier, but i thought that ultrasn0w would take care of it? Any suggestions how to fix this?
well did you use yellowsnow or ultrasnow because you refered to both. go back and make sure you downloaded ultra not yellow. This has happened to me before. What I did was unplug my iphone from itunes and did a reboot. If that doesn't work for you try reinstalling ultrasnow. Hope that helps!
I use ultrasn0w and the unlock works fine. But I can't sync it with iTunes! iTunes check if I have a correct SIM-card everytime i try to sync. And cause I do not have the correct sim-card inserted in the phone, I can't sync it!
