Can I use my iphone without syncing it to my computer?

My laptops been busted for a few weeks now and the only thing I have to use it our home computer. I don't want to sync it to that because I don't want my brother (he has his ipod hooked up) to lose his music. Do I NEED to hook it up? Can I just log in my itunes account stuff on it? And if I do have to hook it up, can it wait like a month or two for when my laptops fixed? I'm only asking because it keeps poping up on things like snapchat that I need to "connect to itunes to use psh notifications" Even when I said I didn''t want them to pop up.

Lol I have caught you second time. It's stolen phone and you are a uneducated thief so I donot think even if I told you how to you will not be able to get it running.
Take sim to cellular company and they will track it back to owner and return it.

You could use home sharing, but that only allows one computer. If you want to permanently sync to your laptop, you have to wait to use your itunes account

  • Transfer purchase without syncing to computer? I have an iPod touch with an app that I bought a long time ago on it. The iPod is currently synced with another computer and I want the app to sync to my iPhone on my computer without syncing to my computer, as it will remove everything from it. The problem is, though, that iTunes doesn't think I've bought the app already and it charges me for it, but I have no money to buy it again. How can I retrieve the app from the iPod without the other computer and put it on my iPhone?
