If you need an excuse to leave a meeting or end an awkward date - let your phone rescue you!

The 'Fake-A-Call' iPhone application lets you act out a call which sounds and looks real to bystanders.

The application offers 9 different oices of fictitious callers to listen to.All you do is talk along.

There are also 9 different scripts to choose from, ranging from a roommate in need, to a problem child phone call.

The Fake-A-Call iPhone app is free, but there are also a number of other similar applications: 'SMS Faker' simulates text messages, 'Fake Call Me' works on Androids, and 'Phoney Call' is one for Blackberry isers.
