The first time the words "Stage UI" passed our lips, they were in relation to the Dell Thunder leak , but now we're hearing that Dell's custom Android user interface will actually appear alongside Android 2.2 when the update finally arrives on the five-inch Streak . We've just learned that's going to happen this winter in Japan when the Streak launches on SoftBank at the very least, as both are advertised for early December there, but we expect we'll see the updated OS even sooner in the US and Europe for obvious reasons . What's more, an unofficial build of Froyo that leaked out for the Streak last month has since been found to have Stage UI on board. StreakSmart's got a video of a custom ROM running a series of Dell-specific widgets on the Streak, and sister site Good and Evo managed to trick the very same software to run on a rooted HTC EVO 4G . You can see examples of both on video after the break, but here's the basic idea behind the UI -- giant panes of contacts, apps and shortcuts that fill an entire screen each, but leave your app drawer accessible at a swipe. If you're feeling daring, you can try the ROM for yourself at our more coverage link. Just be careful flashing that new baseband, eh?[Thanks to everyone who sent this in]
