The port of Android 2.3 Gingerbread over to an HTC HD2 has opened the floodgates for other hacked Gingerbread ROMs, with versions now available for the HTC Droid Eris, Evo, Wildfire, and Hero.
These releases are each home to their own assortment of bugs and hacked-together workarounds, so don’t expect a sleek Nexus S experience out of Gingerbread on any of them. On the Wildfire port, for instance, only the most basic input and phone functionality is implemented. Most everything else, from the camera, to wireless data, to Bluetooth, is broken.
Some of these release are more functional than others, but none of them are going to replace Android 2.2 until a whole lot of bug-fixing is done. Don’t expect any really polished releases until Google publishes the Gingerbread source code. For now, developers are just hacking fixes onto the Gingerbread image from yesterday’s release of the SDK.
As with any unsupported modification to your smartphone, proceed at your own risk, maintain backups, and look both ways before crossing the street. For the current Gingerbread releases for each phone, check out their respective forums over at XDA-Developers.
