Writing Pinyin tones and Downloading Vocabulary list

To anybody,

ChinesePod place in "Ad Ons" which allows you to check a box so that you can turn Pinyin numbers ...i.e. wo3 into the tone marks. But I can't seem to find an explanation as to how to actually physically do this. It just say you can do it .....did I miss something somewhere ?

Also can someone please tell me how I can download my vocabulary list onto my I Touch if that is possible ?

Thanks, Wesley
