There is new problem floating around to the people that are using Data SIMs or phonebook SIMs to activate their iPhone because they don’t have a legit carrier SIM.

After activation with these SIM, the device is jailbroken with jailbreakme.com and unlocked with Ultrasn0w. When the user switched the SIM and insert their carrier SIM, the iPhone will immediately show the slide for emergency screen and if user removes the carrier SIM, the iPhone will go back to the springboard.

FIX:

Here is quick fix If you are having this issue, get the lockdownd from a working hacktivated iPhone 3G/3GS respectively. The lockdownd file is located in /usr/libexec. Copy the file to the device you are having problem. You can copy file using utility such as ifunbox or something similar. The permission on the lockdownd file is 755. If you are copying the patched lockdownd over the existing one, the permissions should be in-tact.

1. Download ifunbox from Here

2. Open ifunbox and connect your iPhone.

3. Download the lockdown from here.

4. GO to /private/var/root/Library/ and replace the original lockdown folder and put the new downloaded folder.

5. Restart your iPhone and hopefully it is fixed.
