Yeah, it's been down for a while now. ShopBlackBerry.com wasn't powered by BlackBerry, but by a third party company who then went bankrupt. Left them without a store, so BlackBerry is now building a new one.
Here's the statement from BlackBerry on it I received when I reached out after it first went down.
“Due to circumstances beyond our control, ShopBlackBerry.com is temporarily unavailable. Customers who have paid for merchandise but have yet to receive it will have their orders fulfilled by RIM as soon as possible. We apologize for any inconvenience this situation may cause.
“We are currently working to restore functionality so that customers are able to continue purchasing BlackBerry Smartphones, Tablets and Accessories from ShopBlackBerry.com in the near future. BlackBerry products remain on sale from a wide variety of retail websites and locations around the world.”
They just updated the ShopBlackBerry store landing page recently to a coming soon for BB10, but for a few weeks before that they were linking out to other retailers. They actually had ShopCrackBerry.com listed as the recommended online store.
I'm sure they're hustling to get relaunched as fast as possible.
