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, which is being referred to as the “death hug.” It should be noted that although early Apple-sanctioned reviews of the Verizon iPhone 4 claimed that the antenna problems had been fixed in the CDMA model, the same reviewers failed to notice the antenna problems in their original coverage of the GSM model. Once again, use of a protective case appears to fix the antenna issue, and antenuation may not be noticeable in areas with stronger signal strength.
PS: ‘death hugh’? oh c’mon, who is really holding the iPhone like that anyway?
