So, according to wikipedia ([URL="http://en.wikipedia.org/wiki/Iphone_4#Design]here[/URL]), the antenna issue may be caused by an ungloved hand touching the two antennae, bridging the signals between the two (previously separated) stainless steel antenna. If this is true, then I may have a theory on how to fix/help the issue.
In theory, if you turn off bluetooth, Wi-Fi, and GPS, this should help the GSM signal from being disrupted by an other signal. Obviously, if this works, its not a long term solution, because people still need to use these features.
Id try this myself, but I dont have an iPhone 4 yet (live in Canada). So, if any of you have the antenna problem, please try this and tell me if anything changes. Im curious to see if this works!
