Last week we told you about a method to fix the “Different SIM detected” error on an iPhone activated with a phonebook card. This method required a bit of file handling and could have scared away the least technically oriented of you.

How to Fix the “Different SIM detected” on the iPhone

Step 2: Go to Cydia and add the following source: http://cydia.pushfix.info.

Step 4: Reboot your iPhone.
Done! You should now be able to swap SIM cards without any problem.
