I found out about this because of DD17, however once I found this out, I immediately KNEW that this is now helping and will eventually be the next big thing for the AP's to keep in contact.

There are apps available for the iPhone and Blackberry that will allow partners to TM, IM and email, all while skirting the usual tracking methods.

One App is HeyWire. It is a remote textmessaging service that will allow the phone owner to send and receive text messages with othere parties, and since this is done via internet, none of this will show up on the phone bill.

Not sure if any of the Flexispy or other phone tracking systems will record this information or not, though.

Thought I would pass on this information to those who needing help in the snooping department....
