Engadget writes in their article that the source indicated that the Dell Thunder is running Android 2.1 with a 4.1" OLED screen and the possibility of a screen resolution higher than 800 x 480. A 1,400mAh removable battery is also said to come in the device.
The video maker doesn't say how he came upon the device, but judging from the high nasally voice, I'd say it was the son of a Dell engineer or tester.
Gizmodo notes that the "phone's screen may be smaller than some others out there, but it looks like a hefty bezel bulks it up some."
Android Central comments that the Dell Thunder and Samsung Captivate "appear to share the same design cues."
Head on over to Engadget to check out the whole collection of photos, and watch the video.
