It provided progress bars for individual file transfers, verbose error logs, and manual conflict resolution dialogs. The "Switch Device Wizard" allowed users to physically migrate data from one BlackBerry to another via a PC—a process that felt tangible and secure, contrasting with the opaque "cloud sync" of today. The search for the download is, in part, a search for this sense of control.
