File this all under unconfirmed/you've heard this all before/we like to torture thee:
From the above Tweet, word has it Verizon employees are starting to receive training on Windows Phone 7--which makes sense as their next step with their forums being cleaned out and the Best Buy listing. So we wouldn't be surprised if we start hearing a bit more about such events over the next few days...
The other thing is we're hearing about a May 12th date. Once again, we've had many, many dates in the past and we really have nothing to show you that this is real this time, but if you believe the stars are aligning for a launch, Thursday May 12th may be your day. Or it might not.
You may now all remount your tin-foil hats. Thanks, @ThePhilFletcher and anonymous, for the info
