Well hello there giant Windows Phone 7 handsets. This interactive sidewalk display was just unveiled at the Telstra store in Melbourne Australia. On the left we've got what looks to be the HTC Mozart already rumored for Telstra. The device on the right, though, is a previously unseen LG Windows Phone 7 device. Best of all is the "coming 21-10-10" text in the fine print that matches up nicely with the rumored European launch date. Don't worry, in a few hours we'll have all the details nice and official like.

Update: The LG phone is the Optimus 7Q.
