Everytime I plug my iphone into sync it automatically goes to the scree "welcome to your new phone" set up as new or restore. I've already set up my phone and synced it before what is going on? I tried restarting my pc even went ahead and restored from my last back up, but still can't get passed the screen "welcome...." No idea what's going on. I'm using my official apple usb. Perplexed??
