According to the NYTimes, the Cupcake Firmware Update isn't really an official Firmware Update at all. In that sense, Cupcake doesn't exist. Instead, Cupcake is a developmental tool. According to a Google spokesperson:
“Cupcake is a tool that we are using to develop future versions of Android”
So it looks like Cupcake won't be delivered to G1 Users in one shot, but rather, continuous firmware updates. How do you guys feel about this? Is a slow trickle of updates good enough for ya? Will RC33 hold you guys over?
