Solution: Error "iTunes cannot copy the iPhone because it cannot sign in"
Hello iPhone users, I'm bringing you the solution to the problem we were having with custom firmware created with Snowbreeze. After syncing, iTunes displayed an error message saying, "iTunes cannot copy the iPhone because it cannot sign in to it." As I explained in the post where I uploaded my custom firmware for the iPhone 3G, this error was due to a problem with Snowbreeze itself, specifically its activation within our firmware.
