A new gadget that is designed to recover information that has been wiped from an Apple iPhone may help people keep tabs on their unfaithful partners.
Manufactured by Paraben, the USB stick - called the iRecovery Stick - can also retrieve deleted contact details and even mapping solutions, which show the destinations that the phone user has visited.
Unsurprisingly, it's proving very popular with those who suspect their other half has something to hide.
"It's also aimed at the employer who suspects foul play from a member of staff and even the police," he said.
The USB stick gadget works by connecting to a computer, which is, in turn, connected to the iPhone.
Once the two devices are connected, the built-in software on the iRecovery Stick retrieves the deleted data on the phone.
The gadget, which costs 199 pounds, has sparked the interest of detectives, who can use the technology to retrieve evidence that may have been deleted from a suspect's phone.
It can also be used in more mundane circumstances, such as retrieving data has been accidentally deleted, including songs on iTunes.
