Well, who saw this coming? Froyo -- yes, the one and only Android 2.2 that got released via SDK today -- has already begun its grand voyage into hacky, totally unofficial device ROMs that are available to unhealthily brave users. The two we've got for your perusal here are for the Nexus One (of course) and Verizon's Droid Eris, of all things; our understanding is that both of them are ridiculously unstable and unpractical for actual use at this point, but it's patently obvious that these guys aren't going to sleep until there are some solid firmware binaries on the interwebs. Mountain Dew Code Red and bottles of No-Doz, fellas.
