iPod touch users are finally getting a taste of what iPhone users have had since iPhone OS 2.2: Google Street View. iPhone 3.0 Software Update for iPod touch includes an update to the Maps application that enables Google Street View, and it works just like it does on the iPhone.
Additionally, the "Find my iPhone" feature is implemented as "Find my iPod touch" for iPod touch users. It works exactly like Megan described yesterday, but is perhaps less accurate than using the iPhone's built-in GPS. It'll at least get you close, so long as it's connected to a Wi-Fi network. If it is, you can send messages to the iPod touch and wipe its memory.
If you do send a message to an iPod touch that's turned off or not connected to a Wi-Fi network, the message is queued until it's on and connected.
Both features appear to work on both first- and second-generation iPod touch devices. As Megan mentioned, since the first-generation iPod touch lacks a speaker, it won't make the "ping" noise associated with Find my iPhone unless you have speakers plugged in. Perhaps less useful for finding it in the house, but still helpful if you left it on a table at the park.
Have you found an undocumented feature that the iPhone 3.0 Software Update for iPod touch provides? Let us know by tipping us, or leaving a comment.
Thanks, Harold, Ben, Rocky, and everyone who sent this in!
