I want to buy an iphone 4s this week. My only issue is, i don't want to hook it up to my pc right now. I want to wait until i can buy a macbook next month to finally hook it up. Would this work? I still want to download apps and stuff through the app store on my phone. How would that work when getting a macbook and finally hooking it up? Would my apps sync to my macbook or be erased when it's connected? I thought syncing only worked from the computer to the phone, not from the phone to the computer?
