Nokia Lumia 900 for Optus in June, sans 4G

Nokia will soon release two new Lumia-branded Windows Phone models in Australia, with the Lumia 900 heading to Optus and the Lumia 610 to Boost Mobile and Vodafone.

Unlike the popular version of the 900 on the AT&T network in the US, the 900 will not be 4G capable in Australia, though it will benefit from dual-carriage HSPA+ data speeds, with a maximum theoretical download speed of 42Mbps.

Optus will offer the 900 in June on a range of plans, including $0 upfront for AU$60 per month. It will be also available through major electronics retailers for AU$699. The Lumia 610 will be available in June through Boost Mobile, and then on the Vodafone network in July. It carries a AU$329 asking price.

Both phones run on Windows Phone 7.5, the latest version of the Microsoft-developed operating system, but are powered by different hardware. The 900 uses a 1.4GHz Qualcomm processor and packs a 4.3-inch WVGA AMOLED display. The 610 also has a WVGA resolution, but its screen is a standard LCD panel. An 800MHz processor is employed in the budget-priced Lumia 610.
