That would be counter productive... instulating the phone will make it worse, since you'll be holding the heat in... the phone, if anything, needs ventilation, to allow it to cool, but, in a perfect world, they would just take more time in working the radios properly...
But, then again, if we weren't so fussy, we could settle for a bigger phone, allowing more air flow through it, or slower phones, so the processors don't have to work so hard, generating so much heat...
