Iphone 3gs stuck half way through updating?

I was updating my iphone 3gs and I think my phone died half-way through… I'm not sure. But it is frozen on that screen. I've turned my phone off and turned it back on, i've held down the home and lock button, and i've let it die. And when it turns back on its still the same screen

.i've been trying to update my 3gs since a year now.nothing seems to work; i think its time to move on even if the machine is still in pristine condition.

  • Will updating my unlocked iPhone 3GS lock it again? My phone is on 4.1 and I wish to update it can I do so without it locking again? And if so can I do it on iTunes?
  • 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?
