Will my jailbroken iphone 3gs lock after updated?

Will my iphone 3gs lock after it is updated to ios 6.1.6 and how to unlock it?
Please answer so i can unlock it.
It is jailbroken.

I don't know if the 3GS can even update to 6.1.6 but if it's jailbroken for sure and has Cydia then I think you need to add a source and install something that will unlock it. You'll find more help on YouTube.

Yes, if you update it will no longer be jailbroken or unlocked.

  • Why Won't My Unlocked iPhone 3GS Activate After I Updated It? I got my iPhone 3GS unlocked, however, it said it needed updated, so I updated it. After it was updated, it won't activate now and I don't know what to do. How do I fix this?
  • Why is my IPhone 3GS having problems after I updated it? After updating my iphone to the latest version (5.0.1I think it was) my phone just randomly started shutting off and coming to a blank white screen and then an error screen and after a few times it went back to normal then shut off again. Right now it is recovery mode and not working so I was wondering if anyone has the same problem and a solution to it.
  • My itunes says it hasn't updated een though I updated it? I went to update my iphone and it said I had to update my itunes first and restart my computer (i have a macbook.) So I did all that and went to try and update my phone again and it still said I had to update my itunes first so I did it again and it is still not allowing me to update my iphone. It still says I need the latest version of itunes. What am I do wrong!
  • My iPhone 4s was jailbroken and I updated to the ios 6? I had no idea that my iPhone was jailbroken since I bought it from my dad's friend and now it's stuck in recovery mode and I tried iTunes to restore it but it won't work what do I do?
