So my phone dropped and cracked the other day, and it hasn't worked very well at all since. The phone completely died yesterday, and I had to restore the phone, so obviously everything was taken off of my phone, and it's on my icloud backup. My only problem, is getting my information back onto my phone. So when I go to icloud.com and look at find my iphone it says there's an option to erase iphone. What happens if I do that and is there a way to get all of my apps, contacts, pictures, and other information back and onto my phone again?
