If our screenshot tour wasn’t enough to satiate your Gingerbread lust, a bunch of Android developers have already started porting the Android 2.3 SDK to various Android devices, so rooted users can play around with it now and see what’s new.
These ROMs won’t get you by on day-to-day use, since they’re just the SDK—certain basic phone functions won’t work on your device when you flash these ROMs. That said, if you just make a backup of your phone before flashing (which you do regularly anyway, right?), you can check out what Gingerbread will actually look and run like on your specific device, which is pretty neat—and then when you’re done just restore to your more functional backup. And, of course, if you like what you see, the new Gingerbread keyboard and launcher are already available for daily use on your 2.2 phone.
The Gingerbread SDK ROMs are free downloads for various rooted Android devices. More ROMs are always being added, so keep an eye on the page below for your own device.
