My 2g iPhone recently took a nasty fall and now has a smashed and unusable screen. The internals of it work fine, and I was wondering if I could use it only as a hard drive. I have transferred service to a new 3g, so this one no longer functions as anything useful. The screen does not respond to touch so using a program on the phone like Airshare isn't an option. Is there a way to completely erase the operating system and all files on the phone and make it show up just like any other flash drive/hard disk?
