In late July, we covered a way to activate iPhone with a what-so-called Phonebook SIM card. Early adopters reported that the method worked great and they could easily hactivate the iPhone without an official sim. Lately, however, it was reported the phonebook sim card does no longer work.

What it turn out is that the phonebook sim hack has brought up to Apple’s attention and they immediately developed a fix to block it out. Recently, if you use phonebook sim card to activate an iPhone, you will get a “Different SIM Detected” error and are prompted to connect to iTunes.

That’s really discouraging when you encounter this kind of error. However, someone has already developed a fix to resolve the “Different SIM Detected” issue.

Procedures to fix the “Different SIM Detected” Issue

1. Restore your iPhone to iOS 4.0.1 via iTunes

2. Once it is restored, insert the phonebook sim card to activate the iPhone.

3. After the activation, remove the phonebook sim card.

4. Open Safari and go to http://jailbreakme.com. Slide the “slide to jailbreak” to kick off the jailbreak process.

5. After the jailbreak process completes successfully, launch cydia. Install both “afc2add” and “ultrasn0w”.

Note: The “afc2add” is a service for USB file browsing and the “ultrasn0w” is to unlock your iPhone.

6. After running ultrasn0w, it is supposed your iPhone is unlocked but you will still receive the “Different SIM Detected” error. Next, download iPhone Explorer, which is a freeware for browsing iPhone’s file system. The software is available for both Mac and PC.

7. Connect your iPhone to computer via USB and launch iPhone Explorer.

8. Browse to the folder /var/root/Library and delete the “Lockdown” folder.

9. Download the patched version of lockdown folder from here.

Note: You need to register before you can download the file.

10. Copy the “Lockdown” folder to /var/root/Library (i.e. the same location as the Lockdown folder you have just deleted in step 8).

11. Restart your iPhone to activate the fix.

That’s it. I hope this fix works for your iPhone. As always, feel free to leave comment and share your experience.
