Unlock iPhone 3GS Baseband 5.13.04 without Using Ultrasn0w (5.14.02, 5.15.04, 5.16.02 too!)

Hello there! If you are new here, you might want to subscribe to the RSS feed for updates on this topic!

OK, this may sound like a strange blog topic, right? Well, we’ve been trying to develop an unlock prototype for iPhone 3G and 3GS for all basebands without the need to jailbreak and use ultrasn0w. We have a video to prove it.

UPDATE: Officially unlock your AT&T iPhone here or any iPhone from other network.

The video above shows an iPhone 3GS, model number MB715 (old bootrom) purchased from Apple Store with AT&T contract, unlocked to China Mobile network. This phone has baseband 5.13.04 that can be unlocked with ultrasn0w but I intentionally removed ultrasn0w to show that this method works.

I’ll try to find a 3GS with baseband 5.14.02, 5.15.04 or 5.16.02 and make the same video, hopefully over the next few days. Unfortunately this unlock doesn’t work on baseband 5.16.05 that comes with iOS 5.

If you don’t wish to update to baseband 6.15.00 to unlock your iPhone, this is your ultimate and safest solution. It will not affect your GPS and other risks associated with baseband 6.15.00.

Stay tuned….

  1. so you have found a way to do this on 5.14, 5.15, and 5.16 also, or only on 5.13?

    If you have another way to unlock 5.13 that is no big news. If you have a way to unlock 5.14, 5.15, and 5.16 that is good new, not a huge deal as this can be done with 6.15.

    Bob.

  2. Oh man I can slap myself with silly. I wish I didnt do the iPad bb on my 3GS 5.14. Just last month i did it. I gotta see if I can get it swapped out.
