A handy little app that is created by developer, John Reid, is called Cheap Rate. You can use Cheap Rate to easily and quickly find cheaper or free phone numbers for UK companies. Simply enter the company name or a premium-rate phone number, and Cheap Rate will offer you alternative numbers to try, saving you some hard earned cash! As you can see from the image above, I searched for 'BlackBerry' and Cheap Rate found a few entries for me to choose from.
This app is only supported in the UK and currently only available for the BlackBerry PlayBook. You can pick it up free in BlackBerry App World.
