Apple appears to be working on a process to allow iTunes users with more than one Apple ID to somehow “merge” them into a single account. The ability to do so will be critical to the early success of the company’s new iCloud service, since it relies on Apple IDs for syncing iTunes purchases and other data.
The problem with managing multiple Apple IDs with iCloud first became apparent when Apple launched an early beta of one of its features called “iTunes in the Cloud.” It allows users to automatically sync iTunes purchases between iOS devices and computers running iTunes. When you link an Apple ID to your iPhone, for instance, any apps, songs, and iBooks you buy from your computer are automatically downloaded to your iPhone (and vice versa).
