The only images we've seen of the upcoming HTC RubyAmaze 4G, the high-powered smartphone inbound for T-Mobile, have left us eager for more substance; few pictures show the phone powered on, and even those offer no visual evidence of its rockin' specs. Our thirst for more info about the beast has been slightly more quenched, as Droid Sans snapped some pics of the prototype proudly displayed at a public gathering. From what we can tell by the snapshots, the device's "about" screen confirms the presence of a 1.5GHz dual-core CPU, 1GB of RAM, a 4.3-inch qHD display and an 8MP rear camera (2MP front) with dual-LED flash. The source tells us that it will come shipped with HTC Sense 3.5 running atop Gingerbread, so don't let these photos -- showing off stock Android -- get your hopes up so fast. All in all, though, it looks like the Samsung Galaxy S II may have a fierce battle on its hands for the title of T-Mobile's Next Top (smartphone) Model.
