The CTIA wireless extravaganza started with a thud today as SanDisk introduced its TrustedFlash memory cards. These cards have built-in DRM (digital rights management) to allow the entertainment corps to release music, movies and much more crappy content for mobile phones, laptops, PDAs and other portables. The result is that consumers will be able to buy downloads from online services, and purchase pre-recorded content on SanDisk's new Gruvi cards.

TrustedFlash cards are highly secure, thanks to an on-board processor, a high-performance cryptographic engine and tamper-resistant technology that are designed to provide much higher level security than has previously existed on memory cards and on most consumer electronics devices, said Yoram Cedar, SanDisk s senior vice president of engineering and the emerging markets business unit.

Samsung is the lead partner on the handset side. And Yahoo! has allied with SanDisk to put its Yahoo! Music Engine software client directly onto the card. (DRM and mediocre software—an infield double play!) None of the announcements I've seen so far mentioned support from any movie studios, or record companies.
