iPhone and iPod touch users may have had a Sirius XM app for close to a year now, but it looks like Android users will soon finally be able to get in on some mobile streaming as well. While there's still no specific launch date, the app is apparently "coming soon," and looks to be mostly identical to its iPhone OS counterpart, complete with support for streaming over both WiFi and 3G. Somewhat curiously, however, Sirius XM seems to be saying that the app will only be available for the Droid and Nexus One, although that's a bit puzzling considering they're not the only Android 2.1-ready phones with fast processors (if those are indeed the only requirements).
