I am traveling and don't have access to my main machine at home for which I sync my iPhone to. But I do have my macbook pro, however I don't sync my iphone with this computer. I am wondering if its possible to use my macbook pro ONLY to update to iOS 8 beta? All my apps and music are synced originally to my iMac at home. Will this be possible without overwriting my apps, settings, and media thats currently stored on my iPhone?
