We’re expecting T-Mobile and HTC to launch the myTouch 4G Slide at an event tomorrow, but we have yet to get a good look at the device itself, save for some blurry partial shots. Well MT4GS still hasn’t been fully exposed, but the pair of dummy unit-filled cases above finally give us a pretty good idea of how the entire handset will look — minus the all-important keyboard, of course.

Codenamed Doubleshot, this dual-core companion to last year’s myTouch 4G (recently released in Canada as the HTC Panache) is expected to feature a 3.7-inch WVGA display, 768MB of RAM, and as its name implies, category 10 HSPA+ cellular broadband. The camera is supposedly an eight-megapixel job, and besides offering up dual flashes, the case photos almost make it look as if it’s endowed with an optical zoom. Thoughts? All should be revealed tomorrow.
