ok... so maybe is wasn't asking the right question.
is there a technical recommnedation? encoding, code, definitions etc... that will help a site appear better on a mobile phone searches?
It does NOT matter what technology you are using to search with.
Search engines do NOT "think";
"Oh errm, Blackberry user, what should we show them?,
"Aha Nokia obviously they want something different",
"Aww $4!| an IPhone! Quick, find the 'Kewl" pages to show",
"Sony Eriksonn. They must be looking for music downloads"
