ROKR 100 Tunes Limit Warning

A possibly annoying limitation to the recent Apple iTunes mobile phone, the ROKR from Motorola has been discovered.

It was reported over at playlistmag.com:

Steve Jobs announced that the ROKR would play up to 100 tracks (including songs and podcasts), yet that figure doesn’t jibe with the size of a standard Flash memory chip. By Apple’s calculations, 100 songs takes up approximately 400MB of memory. Is someone producing a 400MB Flash chip now?

Nope. The phone includes a removable 512MB Flash memory chip (found under the battery in the back of the phone). This chip will hold up to 100 tracks but the number of songs it holds isn’t dependant strictly on the size of the chip (though it obviously can’t contain more than 512MB of data). Rather, the 100 track limitation is part of a DRM scheme that prevents the phone from playing more than 100 tracks.

iTunes 5 keeps track of the number of tracks authorized for playback on the phone so even if your 100 tracks have used only 350MB of the card’s capacity, you can’t add more. Similarly, although you can swap in a new card that contains new tracks, those tracks won’t play until they’ve been approved for playback by iTunes.
