The 9860 features a 3.7'³ touch display, which is the biggest screen ever for a BlackBerry device, as well as a 1.2 GHz processor, 768 MB RAM, 5MP camera, full 720p HD video recording, a flash and over 4 and a half hours battery life talk time. There's also no physical keyboard on the device.
RIM's new slimline BlackBerry Bold 9900 meanwhile includes a width of just 10.5mm, support for Near Field Communications (NFC), built-in GPS, 2.8'³ touch display, 1.2 GHz Processor, 768 MB RAM and a full, physical QWERTY keyboard.
Optus revealed consumer pricing for the Torch 9860 will start from $0 on Optus' $49 cap over 24 months, while the Bold 9900 will be available for $0 on a $79 Optus Cap or Timeless plan over 24 months.
Business customers can expect to pay $0 on a $49 Business cap over 24 months for the Torch 9860, with the Bold 9900 available for $0 on the $79 Optus Business Complete or Timeless plans over 24 months.
Both phones will be available from September 1 through the carrier and are now available for pre-order. Optus has an exclusive period of 45 days before other Australian carriers can offer the two devices.
Optus also revealed the older BlackBerry Curve 3G 9300 is now available for its pre-paid customers, at a total outright cost of $249.
'BlackBerry Turbo Cap will get 12 months free BlackBerry Messenger (BBM) and web browsing via the BlackBerry browser along with access to social networking apps such as Facebook Chat and Twitter,' Optus said.
At this stage it still remains unclear whether any Australian carriers plan to offer the three remaining RIM handsets launched last month, including the Torch 9850, Torch 9810 and the Bold 9930.
