If i plug my Iphone in a new computer, will it erase all my data?

If it does how can i back it up?

Before you plug it in, go to iTunes Preferences > Devices, and untick Automatically sync devices. To create a backup you can right click on your iPhone's icon in iTunes and select Create Backup. Also transfer purchases.

Sharepod is a free program you can use to copy the media you haven't obtained from the iTunes Store from your iPhone as this is not included in the back up.

No. Just backup your data on your older computer and then you can really be tension free.

All you have to do is to keep backup of your data in your harddisk or pendrive.

Pendrive will be enough for you to get it on to another pc as well.

When you login your iphone to another computer, even if it erases your data by mistake, you can restore your data by just plugging your pendrive and boom, thats it.

Hope you like my answer.

  • Will syncing my iPhone erase all of my data? My computer had a hard drive problem so they replaced my computer. I know syncing my iPhone (4s if it matters) to the computer will wipe the current music on my phone, which is fine. I just want to know if it will wipe my other data. Such as pictures, apps, things like that. I would just like to know if it does or not before I sync just so I can save my pictures and things to another place.
  • 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?
  • If you update your iPhone 4S to 6.0.1 through Wi-Fi, does it erase all your data? I have updated to 6.0 before on my laptop in iTunes, but strangely it didn't erase all my data, so I didn't have to back up. I didn't see it automatically back up during the process of updating, so I was wondering if it would erase all my iPhone data if I updated it through Wi-Fi. A few months before, when I updated to 5.1.1 it erased all my data. I'm not sure if Apple did anything to 6.0 that made it not erase my data…
  • If I erase and sync my iPhone 4 in the music library, will it erase my photos? I'm trying to add music to my iPhone 4 and when I go to sync just the music, it says 'erase and sync'. Will it delete my photos? If so, can I right click my iPhone and back it up so if it does delete my photos, I can just back it up?
