Stealth Phone recorder voice activated??Smartphone Recorder Zip

I have a Motorola i415 I would like to install this type of software. I have been researching for weeks but my compter and technical abilities are challanged at best, and the information included with software is limited. I need to know more info regarding installation, Is there software that can be sent directly to the phone from your site? and how would I retreive it. Thank You Wanda
