Will syncing my iphone delete everything?

So basically the first time I put music on this iPhone 5 was at my friends house. I tried doing it on my laptop today and realized if I do I'll lose everything I have on here. I'm just a little confused? Does this mean ill just lose the music or all the apps and photos I have?! And the other question is well is there anyway I can back up my phone on my computer and after syncing it putting everything back on?

Syncing should not delete everything you have. Generally, the iTunes follow the lead of the phone, syncing whatever is on the phone onto the iTunes as part of a backup. The only exception to this is the music, it'll add music to your iPhone as part of the syncing process, if there are new songs you've added to the iTunes.

That being said, syncing music is actually not a default of the process. You have to set the iTunes to sync the music (and in fact you can choose what gets sync and what does not).

But it won't delete your stuff, only a restore using a backup will delete stuff, especially if it wasn't in the backup.

Speaking of the backup, I should warn you now that the backup doesn't back everything up. Any saved data on the phone for games and any songs that was not purchased using iTunes will not be included in the backup.

  • When I connect my iPhone to itunes, will it delete everything? I have never connected my iPhone to my computer but lately it's been acting up so I want to back it up and get the 5 in September if it's out. But I'am scared if I plug it into the computer, it will delete my videos and photos cause I didn't register it on my computer. I'm not a tech guy so yeah. If you guys can give me some instructions, that would be awesome.
  • Syncing my iphone to a new itunes will it erase everything else besides my music? Okay I have a problem, my iPhone is already synced to an iTunes account but I want to sync it to a different one. All I want is the music and I'm afraid it will end up deleting everything off my phone like my contacts, pictures, messages, apps.i've already done it once before but i'm afraid it will delete everything because my friend tried syncing hers to a different account and it completely deleted EVERYTHING.
