Gotcha. Now I see it. Didn't realize the antenna extends across the battery cover. Thanks for the clarification.
Hmm, I'm thinking I can make an antenna using aluminum foil.
I received my Evo 3D battery today and it does indeed fit and works great. Fit is bit tight since the Evo 3D battery is a bit thicker (which actually works since the battery won't be moving around at all.) My TPU case fits w/ slight buldge. Nothing too noticeable and certainly liveable.
We'll see how the OEM HTC 1750mAh battery does vs. stock 1230mAh.
Putting a thicker battery is NOT a good idea. If it expands slightly due to heating while charging or heavy use, it will apply pressure to the screen. OEM batteries are less likely to expand dramatically than the chinese crap-batteries but if it's that thight fit as you describe, even a small expansion may lead to problems with the screen.
