I've been running the Vanilladroid firmware for my HTC Eris for a few weeks now. Beside the phone spontaneously rebooting itself every few hours, its run great, and with built in wifi tethering.
Tonight it proved potentially fatal for one young man. While walking home it appeared like I interupted a mugging near HacDC. The victim was being kicked by a man who ran away as I got closer. He was laying sprawled out on the concrete, face right on the sidewalk and shirt ripped off. I pulled out my phone, hit the icon for Dialer One (which comes with Vanilladroid), dialed 911, dial key, and... nothing. Dial key again, nothing. Checked, it says 911 in the number box, but the app isn't dialing it. I closed the app and tried again, notta. I can't believe it would refuse to dial 911 so I hard reset the phone and try again, still the dialer just sits there as I press the dial key.
I finally had to go on the web, look up the number for Dc Police, and have them transfer me to 911.
I take partial blame for not looking into this app and switching it out sooner. Hopefully Google removes it before someone dies while trying to call for help.
