Step 1: Go to Cydia and install SAM - Repo address:  http://repo.bingner.com

Step 2: Now insert your Unofficial SIM card.

If you still haven't had success you can follow the full troubleshooting tutorial specified below.

In the event that you receive a notification that says: You must select the original carrier SIMID of your iPhone, or almost any other error notification you simply can perform the following steps:

Step 1: Remmove your SIM from your iPhone, open iFile and navigate to /var/root/Library. Now tap on edit inside the upper right corner, and choose Lockdown, and also tap the zip button to make a backup of Lockdown. Scroll to the bottom to make sure that a backup zip was made. Right now remove the Lockdown directory.

Step 2: Go to /User/Library/Preferences and look for SAM, and Remove the com.bingner.sam.plist file.

Step 3: Switch off your iPhone, and Switch it on.

Step 4: Now insert your Unofficial SIM card.

Step 5:Open "SAM prefs" -> "Utilities" -> "Attempt Activation". You'll receive a notification saying that the process can may take a while. After a little waiting your iPhone will respring.

Step 6: Finally you should be on your unofficial network (for example T-Mobile).

Note: Make sure to follow these 6 troubleshooting steps exactly in order for it to be effective. I have tried it almost several times, and it also work for me.

I have just followed these instructions as far as step 3 and now my iphone 4 is asking me to activate my phone (as if I had first purchased the phone)! I tried to activate it using my old tmobile sim and it will not do it, since there is no service going to that chip, I then tried to use my new orange chip and it still wouldn't work!, what happened? Why do i have to activate my phone? or what did I do wrong? carynlouise07@hotmail.com

this method only worked for about 4-5 days then Apple blocked it, no matter how many times you try it it's not going to work anymore, factory unlock is the ONLY way now (and no I'm not selling factory unlocking)
