While I was on holiday, I tried out an iPhone app that I really liked. However, I did not have my computer with me and as it was very expensive doing data roaming from where I was, I decided to use my wife's computer (which we brought along on holiday to keep the kids entertained) and purchase the full version of the iPhone app via the iTunes on her computer. While trying to sync my iPhone with the iTunes on my wife's computer (which only had that new iPhone app), I realized that I might end up getting this new app transferred to my iPhone but at the cost of screwing up all the other iPhone apps on my iPhone. So I stopped rightaway - I now have an iPhone app I wanted but on a different computer's iTunes (my wife's) and I do not know how to get that app onto my iPhone that is paired with my personal computer's iTunes. So, is there a way to transfer a new iPhone app sitting in my wife's computer's iTunes to my iPhone *without* overwriting anything that is existing on my iPhone? Thanks for all help.
