Hacktivation Patch For Different SIM Detected Error On iPhone After Activation With Phonebook SIM
So you were able to jailbreak iPhone, activate without original SIM, and even finally unlock iPhone. But when you finally replaced the phonebook SIM with the unofficial SIM, you are surprised to see the ‘Different SIM detected’ message, asking you to connect to iTunes.
Well the reason for this is that Apple has blocked phonebook SIMs. So here is an easy to use hacktivation patch for your iPhone to get rid of the ‘Different SIM detected’ error, given by Sherif Hashim the same guy who gave us the phonebook SIM iPhone activation trick.

Those of you who already have the pushfix repo in Cydia can go ahead to step 5. This is the from the same author who also gave us the fix for push notifications.
1. When the error ‘Different SIM detected’ is displayed, replace your unofficial SIM with the phonebook SIM. This will get you out of the emergency mode.
2. Start Cydia from your iPhone springboard.
3. Touch on ‘Manage’, then ‘Sources’.
4. Touch on ‘Edit’ and then ‘Add’. Add ‘http://cydia.pushfix.info’ as a source and hit ‘Add Source’. Let Cydia update it’s sources.
5. Now that the repo is added, go back to Cydia and search for ‘Hacktivation Patch’.

6. Install the app.
That’s it. You can now insert your unofficial carrier SIM and will no longer face the ‘Different SIM detected’ error.
