As I get more contacts I realize that it would be helpful to have multiple phonebooks for contacts available. My current Nokia only allows me to select "phone contacts" or "sim contacts" but it would be great to have the option to have a phone book for "business contacts", "relatives", "friends", etc. Then as long as I have the correct phonebook loaded I'd have less chance of sending a text to the wrong person when I am quickly sending a note. If the phonebook linked with the profile it would b even better. Any ideas? Any phone OS or App is ok as long as it is GSM.
