Updating software on iPhone 4?

If I plug my phone into iTunes and update it to the newest iOS, will I lose everything on my phone? Like photos and apps?

Hi

By updating your iPhone, you will lose all your personal data. However, if you create a back-up of your iPhone then you will be fine.

First plug in your iPhone. Right click your phone, and click back up.
Then after a king up, you are fine to update the firmware of your iPhone.
After updating, click restore on the home screen of iTunes of your iPhone.

Its nothing like that, first of all you need to sync all of your personal apps, contact, pics and etc.
when you are done with sync, click on Iphone 4, click on software update, it would be IOS 5.1.1,
download the update, and when you download is complete you will receive a notification on your itunes
"install update on your iphone and back up", and once you are done with your backup you are safe to update your iphone, without any loss of your pics, apps, contacts, calendar, etc…

AND IT IS FOR SURE THAT IF you PLUG IN IPHONE you WILL NOT LOOSE your DATA! I GURANTEE YOU, IF you FAIL TO DO CONTACT ME…

  • Would updating the software on my iPhone (4s) delete everything off it? So I just got a notification to my phone that said new software update. I clicked close because I didn't know wheather it would delete everything off my phone. But if I do update my software, will everything be deleted off of it?
  • Will updating my iPhone software use more space? I currently run on 7.0.4 and I could be running 8.4. I missed a few updates because I only use my phone for music. I have every megabyte devoted to music and I don't really see the point in downloading more software if it is going to take up valuable space on my phone. Would updating my software actually use more space, or would the new updates cause the software to become more compact? Some people tell me that the new software is significantly smaller but I seriously doubt it.
  • Will updating my iPhone's software delete purchased apps and songs? I'm going to update my iPhone's 6.1.4 software to ios 7 when it is released in a few days. Some of my apps aren't available in the App Store anymore so will the update delete these apps off my phone?
  • 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?
