Of course, your phone needs to support the microSD format. As most microSD-capable phones ship with 256MB cards, a 2GB upgrade is a big step up. It will turn your phone into a fully fledged MP3 player; it will also provide more space for photos, and it will be able to store over five hours of 3gp video files. The best part is, you won't have to connect your phone to your computer to transfer files. Simply take out the card and use the supplied adapters to plug it in to your PC or notebook's SD card slot.
