Nokia PC Suite is being replaced by Nokia Suite, which is the newer and more user-friendly application for Windows PC.
Nokia is not developing PC Suite anymore.
With Nokia Suite, you can connect your computer and your phone. Keeping important information up to date on your phone and on your computer is simple, and you can transfer music, and download free street maps to your phone with ease. Nokia PC Suite and Nokia Suite can be installed on the same computer, but you should not use them simultaneously. Note that the latest Nokia phones are supported only by Nokia Suite.
