Fans of the Sidekick will be sad to hear that according to a leaked T-Mobile document above, the device has been listed as discontinued from the 6th of March. Granted this doesn’t mean that customers can’t purchase the device anymore, but we’re guessing that there is only limited stock and that the carrier will no longer be restocking the device once they’ve run out. We’re not sure if this could indicate that a newer version of the Sidekick will be released instead as no evidence has pointed towards that so far, so for now if you’ve been eyeing the device, you might want to hurry before they’re sold out!
