Folk with Macs who keep their Address Book updated have no problem, as are Windows users who are equally as conscientious about it on Microsoft Outlook. But the poor iPhone newbies who do neither have to impose on their Mac/Windows friends to copy and upload their contacts, lest they do it painstakingly one by one.

Works OK, save for the fact that it’s as slow as molasses accessing the SIM card’s contacts; you’d think the iPhone had frozen. (If you get impatient, just lean on the Home button for a few seconds and it’ll kick you out of the app.)
