SanDisk is supplying the removable memory for the Apple/Motorola iTunes phone, the Motorola ROKR - and 2GB storage is possible in 2006.

Last week, SanDisk confirmed that its 512MB microSD card is being bundled with the phone, and that the card is capable of carrying "approximately" 120 songs, though the ROKR has song capacities capped at 100 tunes.

Music mobile leads convergence

"The ROKR mobile phone is an excellent example of the transformation of the mobile phone into an entertainment device," said Nelson Chan, executive vice president and general manager of the consumer and handset business at SanDisk. "Music is an ideal application for handsets that is enabled by the dramatic increases in capacity in very small memory cards."

The microSD card is based on technology that was jointly developed by SanDisk and Motorola, TransFlash. SanDisk calls the technology: "The world's smallest flash memory card form factor".

2GB iTunes phone in 2006?

There's potential for future growth. The company expects to have 1GB microSD cards in limited quantities by late in the fourth quarter of 2005 and 2GB cards in 2006.

This suggests ways future iTunes phones can offer new and higher capacities, and also hints that ROKR owners may be able to carry multiple music collections on their memory cards for different moods.
