The Shadow takes microSD cards, which is fine for sizes up to 4GB, but once you get above that, the format changes to microSDHC (which stands for Secure Digital High Capacity). The difference is that in order to achieve higher capacities, microSDHC has a slightly different memory addressing method than microSD and a theoretical maximum size of around 1TB. That’s a lot of storage. To learn more about SD memory card formats, check out the article at Wikipedia.

You may be wondering if you the Shadow is compatible with this different type of memory, and as reported by forum user Picasosz, they are. He is using an 8GB microSDHC card to store a handful of music and several movies on his Shadow. Right now, you can buy an 8GB SDHC card for about $119 over at the AllShadow.com Store.

If you’re on the T-Mobile network and are looking for a new phone, you’re probably also at looking at other smartphone devices in addition to the Shadow. The below graphic should be of some help in giving you an idea of how the Shadow compares in size to some other T-Mobile devices on the market now.

Seen above front left to right is the T-Mobile Dash (yellow), the Wing (green), Shadow (red), and BlackBerry Pearl 8100 (purple). If you’re looking for the thinnest device, the Dash is the clear winner. That said, the Shadow has very similar dimensions to the Pearl, a device that many consider to be easily pocketable.

The Shadow is here! This thing is slick. Check out this video for Part One of the unboxing. The T-Mobile Shadow has the new NEO interface that takes Windows Mobile to a whole new level of useability.
