Will my iPhone crash if I update from iOS 6.1 to 6.3?

I hadn't gotten around to updating my phone from 6.1 to 6.2, and now the option just came up for me to download 6.3 and I'm worried it will crash. Will my phone be okay or is there anything I can do?

I think it will be ok. I've Avoided a lot of updates and my phone is still fine.

If the phone isn't jailbroken and generally you're using the official updates, it should not crash at all. Back up all your data and just go for it.

No it'll be fine, apple are smart enough not to make their devices chronologically update.

Hi
There's no way that your iPhone will crash if you are updating it. This problem can arise only if you have a jailbroken iPhone. In that case you will need to restore it instead of updating.
Take a backup and feel free to update.

  • Why does Windows 8.1 Update crash my Wi-Fi connection? As soon I upgraded from 8.1 to 8.1 Update, I can only connect to my Wi-Fi connection at home for like 10 seconds, then the connection terminates and I have to restart the modem and it happens all over again. Other devices lose connection when this happens too. When I only login to my network from other devices (one iphone and 1 laptop (at which I'm typing now) the connection does not break.
  • Why does my iPhone 5C always crash on iOS 8? Ok so once i installed iOS 8 on my iphone 5C the apps that i launch always crash. So i just deleted the apps that crash, then when i go to the app store, it always says "can't connect" when my Wi-Fi is working just fine on other devices -,- please any help to solve this problem? (FYI my phone has a small crack on the top with the camera so it might be what's causing this)
  • New update for iPod/IPhone making things crash? I'm not sure if it is doing this to everyone, but I got the newest update- the one they mainly made for iPhone 5 and IPad 2 but it had a few changes for the iPod 4g so I thought why not. The App Store is completely jacked up. It's either extremely slow or every time I go on it, it immediately crashes and I can hardly ever get a new app. Is this happening to anyone else? What can I do about it?
  • New iOS 6 update, find my iPhone update? I don't like the new find my iPhone update is there a way to change back to the old find my iPhone but keep the new update? It's not showing locations like it used to and won't even how me major boroughs like Croydon. Streets are difficult to see, much smaller picture. General *** compared to the older version.
