Worried that some less-than-becoming activities are occurring on your son / daughter / SO's iPhone? Rather than just approaching them directly, Retina-X Studios' Mobile Spy can now be installed on Apple's handsets. Put simply, the software / service combo enables the account administrator to "implant an undetectable rat inside the iPhone; it then squeals to a server, which is accessible via the web." Mobile Spy logs SMS messages, inbound / outbound calls and call durations, and it does so for just $100 per year. Then again, we'd prefer to handle things the old fashioned, more medieval way
, but to each his / her own.
