Engadget has posted images and video of upcoming Dell smartphone called “Thunder”. Information about the device was first leaked in April, but now Engadget has complete details and video of the device through a tipster. Dell Thunder will come with a 4.1-inch OLED touchscreen with 800 x 480 resolution. The prototype was based on Andorid 2.1, but when the device ships (it can be a while, maybe early next year) it will at least get Android 2.2, if not upcoming Android 3. Other features on the Thunder are 8-megapixel camera with LED flash, 720p video recording and removable 1,400mAh battery. Check out the video below to see the phone in action.
