Next time you call someone on their mobile, they might record your conversation.

Everything you say could be preserved for posterity, to be subsequently abused against you in evidence.

It’s a disconcerting thought. You have a bad day at the office. You tell a colleague what you really think of your boss. Not long after, excerpts from that conversation appear on the internet for all to hear.

Or perhaps you explain to your lover the very many ways in which your partner fails to understand you. Some months later you dump that lover for whatever reason. Within hours your partner receives an email. Attached to it is a recording.

You can guess the rest.

It is not good news. Damned by your own indiscretion denial is not an option, entrapment no excuse.

You can but curse the deviousness of others, wonder as to their means and motivation, and quietly contemplate how best to extract revenge.

If you had only known of Rseven Mobile and what they call their lifecache service.

Available without charge to anybody with a Symbian or Windows Mobile handset, or for that matter an iPhone, the lifecache service now allows you to “record all outgoing and incoming calls,” including calls to your voicemail service, “and backup the recording to Rseven.com for playback,” or any other purpose that might take your fancy.

According to Rseven, their lifecache service enables users to backup and sync all the data on the phones “to a secure and private website”.

Perhaps more disconcertingly the service also boasts a geo-tagging feature that identifies your location every time you make a call or receive a text. That location is then shown on the website, together with details of the call or text.

It’s the kind of feature, and lifecache the kind of service, of which our former Home Secretary, the less than lovely Jacqui Smith, would have unquestionably approved.

Similarly, some companies might also see advantages in having their employees signed up to the service.

For example, they could argue, it would enable sales people to keep a record of calls made to their clients when they were out on the road. Disputes as to what might or might not have been agreed would never again occur.

What’s more, should a mobile be lost, all the data it held such as call logs, messages, emails, photos, videos, music, contacts and calendar could be instantly retrieved.

Less beneficially, at least for employees, the service would also ensure that company mobiles were only being used for approved purposes.

Once signed up you could no longer claim you had been in one place when in fact you were in another. So get ready to say goodbye to those afternoons whiled away in the pub or days spent watching cricket, secure in the knowledge that even though your boss can contact you, your whereabouts will never be known.

Technology can offer many benefits. But it also has its disadvantages.

For some, lifecache will prove a blessing. Others may yet think it a curse.
