HTC ThunderBolt at Best Buy

We've seen a number of rumored launch dates come and go for the HTC ThunderBolt -- the upcoming LTE Android smartphone on Verizon. But rumor after rumor has offered little in the way of proof. But we now have some evidence that appears to connect a few dots -- dots that we've been discussing in the Android Central Forums for a day or so now. Check this out:

HTC ThunderBolt boxWe were sent the screen shot you see above earlier this week. Note that it's a Verizon device, with an in-stock date of Feb. 14 (1). Now note that the model is listed as BBY60LD (2). Best Buy does that so we can't (easily) know what device is listed ahead of time. That doesn't tell us much, now does it? But don't worry about it. It's a red herring.

Now look at the number we've circled at the top left (3) -- 044476816574 -- With us so far?

The video has since been removed, but not before Android Central Forums member paulmike3 noticed that number -- 44476816574 -- on the proof of purchase attached to the box from which the ThunderBolt was pulled. It's grainy. It's blurry. But it's definitely there. And it's more than a coincidence.

So you've got the number on the Best Buy leak. And you've got it on the ThunderBolt box proof of purchase. We've connected some major dots here, and it indeed looks as if Best Buy plans to have the HTC ThunderBolt in stock on Feb. 14. Happy Valentine's Day.

Some questions still remain. When will it be available on Verizon? (Feb. 11 has been rumored in the forums.) And is that Best Buy date real, or another placeholder? And how much is the phone going to cost? Big questions, all. And if you've got the answer, you know where to find us. Thanks, Paul, and Fire Dude!
