There are a few subtle differences in the GSM and CDMA models, but as you’ll notice from Engadget’s picture, the dash in the antenna responsible for the original Death Grip is still there. So the reasonable expectation is that the Death Grip would also still be there, but for some reason this didn’t quite sink in to some.
Added to the fire is iLounge’s newly coined term: the Wi-Fi reception-killing “Death Hug” that occurs when you squeeze the Verizon iPhone with both hands. But, as MG Siegler hilariously notes, the Wi-Fi connection will also drop if you set your iPhone on fire, plunk it in the ocean, or cover it in four feet of concrete.
My advice: If you want a phone with a superior antenna, don’t buy the iPhone 4. Go Android. Or wait until the iPhone 5.
