no idea, no one here has announced anything and RIM australia has nothing much to say other than "coming soon".
If its anything like how long it took them to release the torch. Expect it in August or if for some reason they feel like being an arse they'll just wait for the 3g version and Telstra will be the only one to have it and we'll see it in Oct/Nov/Dec (depending on when RIM releases that version)
Shame, Since I see them trying hard in regards to RIM events and marketing teams on the road showcasing their phones but whatever...
