i noticed i assumed a few times they were indentical, but hadnt actually checked.. so i went to HTC to check it out(by the way htc europe page has HTC Tattoo Android showing) ......YES, VZW and Sprints are Identical in every dimension
both 4.57"(L) x 2.33(W) x 0.68(D)

for fun i did telus..
http://www.telusmobility.com/en/ON/h...79/index.shtml its metric 114mm(L) x 63mm(W) x 13.35mm(D) used mss converter and got this 4.49"(L) x 2.48(W) x .52(D) - Telsus' wouldnt work..
so i dont see why VZW and Sprint covers wouldnt be interchangeable..
**didnt do tmo, since theres no 3.5mm jack so you can see it wont fit.
