I originally set up my iPhone 4S 16gb phone in iTunes on my computer. My wife decided to plug her iPhone 4S 16gb phone into my computer, since she has a problem with "losing" charging cables. Now, her voice memos are displayed when I plug my iPhone in, and when I click on the iPhone menu, it goes into the app store. I want to remove her information from my computer, and have my iPhone properly recognized when I connect it to my pc. What is the best way to do this? Thanks.
