I have about 50 people listed in my Contacts list on my iPhone (which is synced on my iMac and iPad). They are all friends and family. I use the same phone/number for my small business in which I have approximate 200 customers and it increases everyday. I do not have those customers contacts on my iPhone because I didn't want them intermingled with my personal contacts. Is there a way to maintain 2 separate Contact lists so that I could scroll down just my personal contacts and keep them separate? I remember looking into this years ago but found that there were some issues with it.
