It seems as news of T-Mobile cutting BlackBerry out of brick and mortar, opting for direct shipments, BlackBerry has opened up ShopBlackBerry to selling unlocked versions of their Z10 and Q10 devices for 449.99 and 549.99 respectively. They’ve broken down the shop into (With Plans) or Unlocked signaling carriers will still likely maintain a BB lineup for some time.
TMobile has been struggling for awhile against AT&T and Verizon cutting out the less than popular BlackBerrys is a logical step. No one’s lining up to buy a Z10. Likely the BlackBerry Z30 will be available on T-Mobile via direct ship, and that they will still have devices in store for demo, just none you can take home with you.
