In configuring data synchronization between two devices, the first device generates a user configuration interface to be presented on the second device. The user interface elicits information from a user regarding a personal information manager (PIM) that is installed on the second device. This information is transmitted to the first device, which downloads to the second device a synchronization application package based on the PIM. The user interface installs the synchronization application on the second device, obtains information regarding data to be synchronized, and transmits that information to the synchronization application. This information may include names and locations of folders to be synchronized and synchronization preferences such as synchronization direction and schedule. The devices may include servers, PCs, PDAs, handheld computers, and wireless phones. The server may be network-based, accessible via the Internet, a LAN, or the PSTN. Alternatively, the connection between the devices may be local or dedicated, and wired or wireless.
