I just had a ideal to look at the ifixit photo of the iphone 4 teardown, and its probably a shot in the dark... but it just came to me that would the out case flex inward on the rubber points?
If this was true the picture below shows the GSM attenna extremly close to the LCD back and could therefor bridge it to the 3g attenna one or the internals via the lcd backplate!
