What are the iPhone unlock types?

Well we have three different types of iPhone unlock, below we will show you all specifications of them and which one is best for your case.

Type 1: Software-based iPhone unlock

As it described on the above title, it’s an unlock for iPhone using software, this software was developed by iPhone dev-team called “Ultrasn0w”. This software was good but the main issue on it, that it’s related to baseband version, which means it couldn’t unlock many basebands on iOS 5 and iOS 6. Ultrasn0w has not been upgraded since two years, so it is not good solution for iPhone unlock these days.

here’s the basebands that are compatible with ultrasn0w:

  • iPhone 3G and 3GS : 04.26.08, 05.11.07, 05.12.01, 05.13.04, and 06.15.00 (the iPad baseband).
  • iPhone 4 :  01.59.00 only.

Type 2: Hardware-based iPhone unlock

You may heard about Gevey SIM, rebel SIM and etc. These are SIM trays which allow iPhone users to unlock their iPhones and work on unofficial carriers. It’s a good solution for unlock but it’s also related to baseband version, which means that your iPhone may stuck on any iOS update and gets locked again.

Type 3: iPhone 5, 4S, 4, 3GS IMEI unlock / iTunes Unlock:

This type of unlock is recommended by iPhone dev-team. Simply iPhone unlock using IMEI will turn your iPhone officially to factory unlocked iPhone, which means that the iPhone’s firmware and baseband are irrelevant. On other words, you will be able to update to any future iOS version as it will not re-lock again.

What is IMEI? This is a 15-digits code which is used by Apple and carriers to identify each iPhone.
