Details about the 3G iPhone's Australian launch seem to have been released here on the Australian MacTalk forums. If true, we're seeing a launch of the new 3G version of the phone to coincide with the opening of the first official Apple stores in Sydney and Melbourne, in the last week of June. The big news is there is no contract lock in and it will be able to be used with multiple carriers. All carriers here support 3G. Only one supports EDGE which confirms that the new phone must be 3G capable.
