June 24, 2009 While we're still waiting for AT&T to announce when tethering will be available here in the U.S. (let alone how much it's going to cost), the people of Australia will get to sink their teeth into tethering at no extra charge, starting right when the iPhone 3GS launches there on Friday, June 26, courtesy of Vodafone. The offer is their attempt to beat the competition, Optus, which also will be carrying the 3GS. Tethering will be enabled for all users at no extra charge, but Vodafone will be offering the ability to add on an extra 1GB for $24.95 or 2GB for $29.95 in case they run out, starting August 2009. http://www.iphonealley.com/news/vodafone-australia-to-offer-tethering-free-with-limited-data-plan? America: No competition between service providers, No free tethering. Australia: iPhone on mulitple carriers, Competition results in free tethering.
