Will iOS 6.1 erase my iPhone 5 data?

So the update came a while ago and I was thinking of updating my iPhone. However I'm afraid that it might erase all my data. So if you already tried it, please tell me if its ok to update my iphone 5?

Of course it won't erase your data. It comes from Apple, so there's essentially no chance of it being malicious. It's just an update. In fact, everything that you can download to your phone has been approved by Apple - It won't destroy your stuff, and if it does it will explicitly warn you. Also don't forget that you can backup your phone on the computer.

  • 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.

I have upgraded my iphone 4s to the new iOS, and then a few days later, tried connecting my device to my PC ( i have the new itunes).It, however, tells me that it can't connect to my iphone and that i should go to 'Preference' and select to 'restore to factory' settings. Will this erase my data and 'degrade' my phone to the previous iOS?
