I lost all my contacts - any help restoring them will be greatly appreciated! I accidently let the battery run out on my IPhone 4 and after I plugged it back in and it came back on all of my contacts were gone. Everything else is still on the phone but the contacts are gone. I am technologically challenged and did not realize that I haven't backed up the phone since September of 2011. I thought that when I synced the phone that WAS backing it up. Evidently not. So I am begging for some help. I have looked at some other posts but they all are about losing contacts after doing an update. Please help if you can. Thank you!
