We’ve already provided you with the download links for Apple’s latest iOS 6.1 firmware. Today, we are going to cover iOS 6.1 unlocking and baseband updates.

unlock iOS 6.1

We are going to show you how to use all unlocking solutions on your iOS 6.1 device. The solutions include Gevey SIM, SAM ticket, ultrasn0w and the best – IMEI unlocking for iPhone 5, 4S, 4 and 3GS.

iOS 6.1 basebands on iPhone 4, 4S, 3GS and iPhone 5

The basebands update as well along with the firmware. iPhone 4S, 4 and 3GS users get to keep the old baseband through iOS 6.1 custom firmware creation. The list of iOS 6.1 basebands is posted below:

  • iPhone 5 baseband 3.04.25
  • iPhone 4s baseband 3.4.01
  • iPhone 4 baseband 4.12.05
  • iPhone 3gs baseband 05.16.08

Unlock iOS 6.1 Using Gevey SIM, X-SIM or R-SIM Card

There is sad news for Gevey SIM users because there no solution for the latest iOS 6.1. R-SIM, X-SIM and Gevey SIM users should stay away from the update to avoid getting their device locked again.

How to Unlock iOS 6.1 using Ultrasn0w

Ultrasn0w users have to wait for jailbreak to arrive. Only A4 devices can be jailbroken tethered, but they need to preserve baseband with iOS 6.1 custom firmware. We recommend you to wait for the official guide to get released. You can read our iOS 6.x ultrasn0w unlocking guide posted here.

iOS 6.1 Unlock by IMEI
Factory Unlock iOS 6.1 iPhone 4, 3SG, 4S and 5 via IMEI

Unlock iOS 6.1 Using SAM Tickets

Sam unlock is the best, provided activation tickets have been saved. The users who have them saved can unlock iOS 6.1 at any moment. If there is no activation ticket, it’s best to ignore this update or any other. iPhone 4 and 3GS users can go ahead with tethered jailbreak and restore their activation tickets, but iPhone 4S users still have to wait for the IOS 6.1 untethered jailbreak release.

Factory Unlock iOS 6.1 iPhone 4, 3GS, 4S, 5 via IMEI Code

Out of all the methods mentioned above, factory unlock is the best for iOS 6.1 firmware. The IMEI method unlock can be used permanently, and there’s no need to worry about re-locking when iOS 6.0.1 or iOS 6.1.1 gets released. This is because this unlock will give freedom to update to latest firmwares and basebansds, as the IMEI is secure in Apple’s database.

Our official partner, OfficialiPhoneUnlock, can easily provide IMEI unlock for iPhone 5, 4S, 4, 3GS on any iOS firmware including iOS 6.1, 6.0.1, 6.0 and 5.1.1 on all basebands. Order iOS 6.1 unlock right now.
