My iphone screen is broken and i can't back it up?

My iphone screen is cracked and the display doesn't work nor does the touch sensors. I'm buying a new iphone and i want to back up the old one but i need to enter in my passcode first which i can't. Is there any way of bypassing this?

No you will need a new screen assembly becasue if you can't enter the passcode you can only wipe the iphone by entering it in to DFU mode and restoring it with itunes you will lose all of your data.
