 We Collected Four Methods To Unlock Your iPhone

Method 1: Ultrasn0w

This is the most public method available for iPhone unlocking. As you know Ultrasnow working is based on  iPhone basebands (01.59.00 / 04.26.08 / 05.11.07 / 05.12.01 / 05.13.04 / 06.15.00) these basebands can be unlocked using Ultrasnow. It is to remind you that a jailbroken iPhone is required to install Ultrasnow on your device.

Unfortunately Ultrasn0w doesn’t support the latest basebands ( 02.10.04 / 03.10.01 / 04.10.01 / 05.14.02 / 05.15.04) and we still waiting for the lastest Ultrasnow by the Dev-team that will unlock all above mentioned basebands.

Method 2: Gevey SIM

In this method you have to use a special SIM and call at 112 emergency number to get your phone activated, which might be illegal in some countries. Moreover it does not support all firmwares and basebands So it only unlock iPhone 4 running iOS 4.1 and 4.2.1 basebands 2.10.04 and 3.10.01. You will found troubles on following some steps on every reboot to get the signals of unsupported carrier. In contrast to Ultrasnow, you also have to pay few bucks to get it.

Method 3: Rebel Micro Sim Card.

Rebel Micro Sim Card may be similar to Gevey SIM, Rebel Sim can unlocks iPhone 4 basebands 1.59.00 / 03:10.01 / 02.10.04 / 04.10.01 running iOS 4, iOS 4.1, 4.2, 4.2.1, 4.3 & 4.3.1. The Rebel Micro Sim developer may be trying to solve the Gevey sim  Problems
Rebel Micro Is like an Untethered Jailbreak means if you reboot your iPhone so you don’t have to do the procedure again and again. The signals will come up automatically.
It costs GBP 40 for Rebel Pro and GBP 30 for Rebel Lite. We don't know more about the that sim or the sim problems cause it sill new sim

Method 4: IMEI unlock
