How to backUp an iPhone with a black/blank screen? Recently I dropped my iPhone 4 and when I picked it up the screen was all black but the sensor was still on. I called Apple and basically they said they can try to repair it or just buy a new one. So, I'm buying a new phone. 

As I want to still have all my information, I'm trying to make a backUp, but when trying an error prompts asking me to unlock the iPhone, which is something I can no longer do as I can't see the screen nor does the touch screen work.

So is there anyway to get around that or another way to unlock?
I think your best bet is to to run your iphone side by side with another iphone that is also set to lock.  Now, by using the two phones side by side, you should be able to enter your passcode 'blind' using the position of the keys on the working phone as a guide.
