SanDisk has begun shipping its 8GB microSDHC and M2 flash memory cards. The company is aiming the new cards squarely at users with mobile phones that accept memory, and launching a “Wake Up Your Phone” campaign to increase awareness of the sometimes overlooked capability.

The 8GB microSDHC an M2 cards are now available in major retail outlets worldwide with suggested retail prices of $140 and $150 respectively.
