Will updating my iphone 4s iOS erase my apps?

I have an update available to a version 6 for my iPhone 4s, I have the memory space needed but I'm afraid i might lose my apps and the data that is with em. Will it erase my apps? Or will they be there when the update finishes?

No.

It's possible, but it should not happen normally. I suggest you back up your phone beforehand.

Nothing will change. It's just updating your software. However there have been cases of it deleting some contacts and data but it's a rare occurrence.

No, but you'd better make a backup of your data.

Everything will still be there as you left it when the update is finished. Leave it alone until it has finished updating fully. People tend to lose stuff when they interrupt the process before it has had a chance to complete the update.

Updating the software on your iPod, iphone, or iTunes do not mess with whatever files are on your devices. The only way this can happen is by syncing, or deleting or unplugging your iphone while its updating.

only a RESTORE will delete your files.

However having a backup on your computer isn't a bad idea, for that just in case factor.

  • Will updating to Mac Osx 10.6.8 Erase Data? My iphone's running ios 6 and it got messed up so i wanted to restore it, itunes says it needs to be updated so when i downloaded itunes 7.1 it said mac needs to be updated. Do i have to install the mac osx update? Will it erase my data? ( i don't have a time machine or a back up)
  • 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?
  • What will erase and sync erase on my iphone? I wanted to connect my iphone to a new computer but it says erase and sync, what will it erase? All of the contents or just music?
  • Update apps without updating ios? I have a jailbroken iPhone 3GS with IOS 4.1 so can't update the software to IOS 6.0 in iTunes, else the phone is permanently locked. I want to download some apps including whatsapp but they keep telling me that they require IOS 4.3 or higher. How do I go about installing these apps, especially whatsapp? any cydia tweak or something?
