I've suddenly started having issues with my iPhones home button. Instead of sending it in and losing my phone for days, I'm taking it to an Apple Store a couple of hours away. Is there any file I can take with me on a thumb drive to completely restore the new warranty phone to the settings of my old phone? I don't have a laptop to take with me, but I'm thinking there's gotta be some file I can grab so I can be back to normal as soon as I leave the store. Can this be done? Thanks!
