By now, we all know that HTC is working with Verizon and Sprint to bring Android 2.1 (with Sense) to the Eris and the Hero. We’ve seen a few leaked versions of Android 2.1 with Sense in the past (including the infamous Espresso build) but this is the first build we have seen with the Eris’ name attached.

The ROM was leaked last night on XDA-Developers by someone who claims to work for HTC in China. At first glance, there were a few issues with the files, but after some quick work and tweaks, the developers were able to get the ROM loaded up on the HTC DROID Eris. A few developers are already hard at work, trying to port the build over to the CDMA Sprint Hero.

From reading through the forums, this appears to be the same build of Android 2.1 with Sense as we saw of the HTC Legend that was unveiled at Mobile World Congress, though there are a few things that have been left out (live wallpapers). There is no indication that this is the final 2.1 build for the HTC Eris or when the final build will be pushed out to the Verizon handset.

NOTE: Leading any ROM onto your phone could cause it to stop working. Proceed at your own risk.
