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?
