Hello, I downloaded ultrasn0w from cydia on my 3gs. After I installed it, it rebooted my device. Is my 3gs unlocked now? I can't really tell because I don't have a non-AT&T sim as of now. Thanks!
which firmware?
the 4.0-4.0.1 unlock for the new baseband hasn't been released yet.
Yes, it works with 4.0 and 4.0.1 firmwares baseband on 3G and 3GS.
Not for the iphone 4 if thats what you were thinking.
I followed all the steps posted (jailbreak via jailbreakme.com, installed ultrasn0w,reboot) but when I swap SIMs the 3GS says it can't recognize the SIM and asks for me to sync with iTunes. I'm going from ROGERS to Fido with no luck.
Try reinstalling ultrasnow.
The phone asks you to sync with itunes?
What message does it give?
