If you are using one of the the latest Nokia phones, you can only connect your phone to a PC via Nokia Ovi Suite as they are not supported by Nokia PC Suite. Nokia PC Suite will eventually be replaced by the newer, more user-friendly Nokia Ovi Suite application for both Windows and Mac.
With Nokia Ovi Suite, you can connect your computer, your phone, and the online world of ovi.com. Keeping important information up to date on your phone, your computer, and on ovi.com is simple, and you can share your photos and videos, transfer music, and download free street maps to your phone with ease.
Note: Nokia PC Suite and Nokia Ovi Suite can be installed on the same computer, but you should not use them simultaneously.
