IPhone 3GS (Jailbroken) Updating it from 5.1.1 ti iOS 6.0.1?

I Have a jailbroken iPhone 3GS on 5.1.1, now i want to update it to 6.0.1 but i'm afraid beacause i don't know if my iPhone will work. Any suggestions? ITunes and factory reset or something else?

Help, As soon as possible!

Thank you

Added (1). Factory reset needed or not?

It will absolutely work, however you will not have a jailbroken iphone anymore. The update will go through and reset everything. But that isn't a problem, I'm sure you know how to jailbreak your iphone again because it is very simple either way.

The update will work and you will not brick your phone, although you will lose your jailbreak and there currently is no untethered jailbreak available for 6.0.1 (although there's one that is semi-tethered)

Basically a semi tethered jailbreak allows you to shut down and reboot tour phone whenever you want to, but if you want to use mail, safari, cydia etc. Then you will have to plug in to your computer and run redsn0w through it to boot up your jailbreak.

  • Will updating my iPhone apps affect my phone speed as how updating the Operating System (OS) will? Currently I'm using the iPhone 5s on iOS 8.3 I know if I were to update my phone to the latest OS I may notice some slowdown on my phone's performance, since it may not have the "muscle" to handle certain functions. Many apps now are optimised for iOS 9 and/or the 6th generation phones. Will my 5s' speed performance slow down if I update my apps? Will the app's performance slow down?
  • Will updating Iphone 3GS to ioS 6.0 ruin screw up my jailbreak? I don't know how to ask this… Sorry if my wording makes no sense. I have an Iphone 3GS, and I want to update it iOs 6.0, but won't that take the jailbreak or whatever off? And I will have to jailbreak it again?
  • Updating jailbroken iPhone 4s iOS 5.1.1 to 6.1.3 help needed? Full story: I bought my iPhone off a friend, who previously got it on bill pay, but stopped paying the bill, so they disabled the phone. He got the phone jailbroken to bypass that, and now the phone is working properly, pay-as-you-go, but it is jailbroken. The phone will NOT work without being jailbroken. I was wondering how do I update it from iOS 5.1.1 to iOS 6.1.3? (Keeping in mind it NEEDS to be jailbroken to work)
  • Updating jailbroken iPhone 4 to ios 7? What happes if I update my jailbroken iPhone 4 to iOS 7? I've wanted to get rid of my jailbreak for some time anyways. I'm just curiouse what would happen.
