Hi. I'm on vacation, and I purchased a city guide directly onto my new mac. Unfortunately, if I am to sync my iphone to my new mac, I'll lose all my current apps on my iphone. (My main computer w/ apps on the hard drive is my pc back home across the country.) I can't just download my newly purchased ($15.99!) city guide from my mac to my iphone without wiping my previous apps, which I want & need. Is there a way I can put my new app onto my iphone without losing everything else??? Thanks so very much, in advance.
