Why can't I just add a ringtone from my desktop to my iphone without it deleting the other ringtones I have on the iphone? My macbook recently crashed and my gf lost the ringtones she had on it. She made some new ones and wanted to sync them to my iphone, but the iphone wants to delete her old ringtones because they are no longer on my computer. This seems sort strange. If microsoft did this, they would be called Nazis. Also, I originally sync'd my phone up to my macbook, but later hooked it up to my desktop to try and delete some apps.. lo and behold, it deleted a few apps, rearranged my icons, and deleted some critical info from my calendar. I had never had problems using Windows software, but maybe I am missing something or is this extremely un-intuitive? What are the basic ways to do this without losing things on the iphone?
