My dog dug up an old iphone 3g 8gb phone today. Unfortunately the screen is cracked and I put the phone in DFU mode, tried to install 4.0.1 , but it keeps getting errors so I don't think I can do anything with it. I was able to remove most of the sand, but it unfortunately won't install an OS. I'm able to get itunes to recognize the phone, and am even able to see the apple logo, but nothing past that. What are my options??? Or is it even fixable?
