Guinea Pigs can gain access to thousands of free games, ringtones and graphics just by agreeing to receive three text (SMS) messages a week. This impressive service is being offered by mobile advertising specialist, Pitch, in order to test the waters. Consumers text the word 'Pitch' to 87000 and join up via Pitch's WAP site. In order to receive free content, Wapsters merely need to answer nine questions which helps Pitch build up a profile about them.
