There is a great new post at [GAS] by JR Raphael about how easy it is to install spying software on a cellphone. It should be noted that it is also easy to install the software on any phone you can get your hands on, so be sure to maintain control of your phone. And if you are a real psycho and want to spy on your spouse or girlfriend, the article points you to a site that can help you do it.
Remember, Virginia has already used cellphone records to locate deadbeat dads. They might soon turn on the tracking software and send the cops to pick them up. The courts have already approved using cellphones to track drug dealers.
