Hi, I just got my iPhone 4 unlock on iOS 4.3.3 with Ultrasn0w 1.2.3. However, for some unknown reason, T-Mobile as well as other international SIM card doesn’t work on my iPhone 4. I even asked the cell phone technician to fix but still no success. I searched the web for possible solution and I have found out that I need to get activate my iPhone using the official locked iPhone SIM card. But the problem is, since this I am not the original user of this phone, I don’t have the official SIM card. Please help guys, I need to get this phone working. Thanks.

So, in order to activate your iPhone 4 on iOS 4.3.3, all you need is download and install SAM through Cydia. To do that, just simply launch Cydia app on your jailbroken iPhone and then tap on Manage tab followed by a tap on Sources section. Now, tap on Edit button on the top-right followed by tap on Add button on the top-left and enter http://repo.bingner.com as a new Cydia/APT URL and tap on Add Source button. And then tap on Search tab and type SAM in the search field. From the search result, choose SAM and install it, then reboot your iPhone afterwards. Once downloaded and installed, you can check this post for the rest of iPhone activation process using SAM.
