Can't sync my iPhone, it asks to unlock.

Hey, I crashed my phone last night and the screen is completely shattered so i can't unlock my phone or anything, I want to do a back up so ill keep my stuff but when i connect it to iTunes it says that i need to unlock my phone which i can't, i have iCloud but i don't know if iCloud does a backup itself? so any ideas how i can move my data to my new phone? Thank you.
