With BlackBerry facing a tenuous and uncertain future, T-Mobile has decided it's time for a shift in strategy. According to Reuters, the US carrier will no longer stock BlackBerry devices in its retail stores citing weak demand among everyday consumers. Instead, T-Mobile will now ship in-store and online orders directly to buyers. VP David Carey told Reuters that enterprise and business customers represent a large percentage of the BlackBerrys that T-Mobile does sell, and the company will still have demo models of BlackBerry handsets on hand at its stores — you just won't be able to take one home. Sales may not be halting entirely, but this isn't exactly a strong show of support from T-Mobile. Other carriers following suit could spell significant trouble for the storied phone maker.

Update: While T-Mobile may be removing BlackBerry devices from store shelves, All Things D has learned that Verizon and AT&T will be carrying on as usual for the time being.
