Cnet.​com.au is report­ing on a rumor from “an indus­try insider that wishes to remain anonymous” that Optus will begin sell­ing the iPhone in the last week of June, about 7 weeks from now.

Optus plans to make the announce­ment mid-​May ahead of Apple’s World­wide Developer’s Con­fer­ence on June 9 in San Fran­cisco where Apple CEO Steve Jobs is tipped to launch the next gen­er­a­tion of iPhone.

The arti­cle also men­tions that Apple them­selves may sell unlocked iPhones, which would set an inter­est­ing prece­dent con­sid­er­ing the 5-year exclu­siv­ity arrange­ment Apple have with AT&T in America.

It has also been rumoured that Apple may intend to sell the iPhone directly through Apple stores and resellers, and that these phones would be unlocked.
