Rebecca Black Helps Telstra Launch 4G in Australia

Telstra celebrated the launch of 4G LTE services in Australia (the country's first taste of 4G, with Optus and Vodafone to follow next year) with a campaign called "The Fun Has Just Begun."

The communications giant brought some fun to Sydney's central business district. The public was treated to musical pop-up events including free performances by Friday phenom Rebecca Black in her first big endorsement deal.

Other free performances included a mariachi band and breakdancers around the Sydney CBD, while a flash mob removed their colored t-shirts in unison to reflect Telstra's bright new look. Watch more of the launch event marketing below.

And here's a customer testimonial from Sydney-based producer Warwick Boulter about how 4G will help his video business:
