Windows Phone 7-certified microSD cards hit AT&T store shelves

After a warning from AT&T that customers should only be using officially certified microSD cards in their Windows Phone 7 devices, customers have been left in the dark as to when they can expect such approved storage to become available. Today, Engadget has received word that certified microSD cards have finally made their debut at an AT&T store, presumably with more to follow later.

The 8GB Class 4 cards are made by SanDisk, but the only indicator of SanDisk's involvement is the sticker on the card itself. Elsewhere, Microsoft reigns supreme, with a blue Windows Phone orb in the corner and an overall design bearing a striking similarity to the Xbox Live branding.

AT&T had warned off customers from using non-certified cards out of fear of an impact on performance. In a Microsoft support document, the company wrote that ''Several other factors, such as the number of random read/write operations per second, play a role in determining how well an SD card performs with Windows Phone 7 devices.''

Customers inserting memory cards into their Samsung Focus soon discovered that the OS treats the internal storage and SD card storage as one and the same, making it impractical for removing and inserting into other devices. While no word has been given as to whether this situation is going to be rectified, a boost in overall memory storage is still a welcome addition.
