iLounge is reporing that the Verizon iPhone 4 has anntenuation issues like the AT&T version of the phone. The testing so far has found that the Verizon iPhone 4's issues appear in the same geographic location as the AT&T iPhone 4's, indoors with an average of three bars of signal strength. Once again, use of a protective case appears to fix the antenna issue, and antennuation may not be noticeable in areas with stronger signal strength.
As seen in this Verizon iPhone 4 antenna attenuation video, the CDMA iPhone 4 can still lose substantial cellular signal strength when held in the prior "death grip" position, as well as Wi-Fi signal when held in a different position, in each case noticeably slowing or completely stalling the reception of data.
The problem with Wi-Fi reception appears when the device is held snugly in landscape orientation with two hands, a position common when playing games or using the widescreen keyboard. Prior to the Verizon iPhone 4's launch, which was being referred to as the "death hug."
