The final version of the iOS 6.1.3 firmware is out and its unlocking procedure is also available for your factory locked Apple iPhone 5, 4S, 4 or iPhone 3GS.

There are a number of methods which can be applied and include SAM unlock, X-sim, R-sim card, Gevey SIM, ultrasn0w and IMEI factory unlocking method.

IOS 6.1.3 Basebands on iPhone 4, 4S, 5 and 3GS

It is general knowledge that when the operating software of the smartphone is updated, its baseband gets updated too. Or in technical terms, the firmware and baseband both are updated. It is possible to maintain or conserve the original baseband by using customized firmware that doesn’t cause baseband update. The baseband detail is as follows:

  • iPhone 4 — Baseband 4.12.05
  • iPhone 4S — Baseband 3.4.03
  • iPhone 5 — Baseband 03.04.25
  • iPhone 3GS — Baseband 05.16.08

Ultrasn0w 1.2.8 unlock iOS 6.1.3

The version ultrasn0w 1.2.8 can be used to unlock the latest iOS firmware (6.1.3). When doing this, it is important to preserve the baseband. For more unlocking info, follow our utlrasn0w 1.2.8 unlock tutorial.

Unlock IOS 6.1.3 with R-SIM, Gevey SIM or X-SIM

As many users would know, it is possible to unlock using a Gevey SIM or similar alternates like X-SIM, R-SIM etc. However, the distasteful news in this regard is that this method cannot be used in the case of iOS 6.1.3. Updating would lead to relocking. In the case of users having the baseband 4.10.01, then it is possible to conserve the baseband and update the latest firmware. This is for Gevey sim users on iPhone 4, but it isn’t guaranteed to work.

SAM Unlock Method for iOS 6.1.3 firmware

Those users which have activation tickets can unlock the latest firmware. If in the case, if the ticket has not been saved, it is advised not to update, since it would lead to relocking of the device. Follow this tutorial to restore the SAM unlock tickets on iOS 6.1 / 6.1.3 firmware.

Factory Unlock iOS 6.1.3 iPhone 4, 4S and 5 by IMEI

When it comes to the best method for Unlock, IMEI method takes precedent over others. For unlocking 6.1.3, the best ways to go for it is via the factory unlock method. The important thing about this solution is that it is permanent and there are no issues of relocking. The updating process applies to both the firmware and the baseband. With your IMEI saved in the Apple database, there is no problem at all.

Different services for unlock are available, but some are more reliable and cost effective too. Furthermore, the coverage capacity is also important. Here, it is possible to unlock greater number of carriers including AT&T, Sprint, Rogers, Fido and other main ones. The firmwares include iOS 6.1.3, but it also includes the previous ones such as iOS 6.1.2, 6.1.1, 6.1 and 6.0.

After the unlock, you can update to latest firmwares and basebands without the slightest worries. For getting your device unlocked on iOS 6.1.3 permanently forever, go to this link.

    What about Gevey ultra s sim of 4s can it be used to unlock 6.1.3.

  • bilal

    how to activate 4s ios 6.1.3 ..? plz help someone

  • UnlockBoot

    You need to factory unlock this device. After receiving your confirmation email you will be able to activate your phone with any sim card.

  • UnlockBoot

    No. Gevey Sim isn’t updated to support iOS 6.1.3 firmware. R-sim card works for some carriers, but I recommend you to use factory unlocking. Good Luck!

  • Ali Nasir

    unfortunately my iPhone is locked with BELL, only few unlockers are supporting it and they are demanding a lot for unlock.

  • Rique

    UnlockBoot has to update this site!!!! the unlock for iPhone 4 iOS 6.1.3 (Baseband 4.12.05) by SAM and Ultrasn0w is not working.. you people are out dated!!!

  • UnlockBoot

    Hello -at-Rique Please read the article it says clearly: The ultrasn0w unlock will works if you preserve your baseband. SAM unlock work on iOS 6.1.3 firmware but the jailbreak is still tethered (with Sn0wbreeze) — SAM unlockers should stay away from IOS 6.1.3 updates. Good Luck!

  • UnlockBoot

    Yes it will works. Create custom iOS 6.1.3 firmware using Sn0wbreeze to preserve your baseband.

  • help

    can i unlock iphone 3gs (BB. preserved) 6.1.3 with ultrasnow ??

  • Jeremie Chaidakis

  • UnlockBoot

    Factory unlock works with ANY new & old baseband. If your iPhone 3GS is unlocked using ultrasn0w you need to preserve your baseband with sn0wbreeze before you update to iOS 6.1.3. Good luck!

  • danny

    i currently have an iphone 4s that is locked to fido canada…I recently bought a gevey ultra s unlock sim.. I was wondering if thephone currently has 6.0.1 should i update to 6.1.3 before trying to unlock?

  • UnlockBoot

    No. You can try to unlock it on iOS 6.0.1 if no success we can factory unlock it.

  • danny

    ok.. if i do update will it still be able to unlock with gevey? i figured it would be better to have a newer operating system cause im assuming you can’t update it once its unlocked.
