This SAVES YOUR CONTACTS to Outlook, integrates your Outlook calendar with the datebook on your phone, and lets you save the pictures you take against the inevitable day you drop your phone in the, er, sink. It also lets you create your own ring tones from any MP3. For the price, it's indispensable. Without a way to back up the info on your Razr V3 (which still has one of the best ranges available on a phone) it's a dead letter. This works fine on a Win 7 Pro 64 bit platform- IF you download the win XP virtual machine (FREE APP from Microsoft- lets you run most XP programs in Win 7). Note Bene: if you buy a "new" Razr, it may come with a version of Phone Tools- but older, and quite possibly impossible to update.
