The specs are certainly high-end. Under the hood will be a 1.2GHz dual-core processor and the Revolver will be sporting a 4.3 inch display. An 8MP camera is on the back, and on the front will be a 3MP camera. There is 1GB of RAM on the phone along with 16GB of memory on-board. The tipster says to expect this model to be launched sometime in Q3, but did not mention any possible price for the phone. He did say that this spring, AT&T's web site will show the device as "coming soon".
If true, the Motorola ATRIX 4G might have a very short reign as AT&T's flagship model.
If Engadget's tipster is correct, the HTC Revolver will be powered by Android 3.0 and offer a multitude of high-end specs
