T-Moible has announced today that they will be offering up pre-orders of the BlackBerry Q10 to business customers starting on April 29th. It's not really much to go on but it's a step in the right direction.
Sadly T-Mobile doesn't note anything about a release date, availability or even a price - so you'll just have to hang tight until a "later date" when the details show up.
Nothing yet from Verzion, AT&T or Sprint on the Q10 either but fingers crossed we'll see some news soon.
You can head to business.t-mobile.com/blackberry-q10 starting on the 29th to register.
