Samsung has inadvertently revealed a new Android flagship in one of its spec sheets. The i8520 -- to be labeled the Halo in a formal launch tomorrow -- should be Samsung's first phone using Android 2.1 and should be the company's most capable smartphone to date. It will use an even larger 3.7-inch version of the Super AMOLED screen found in the Wave and will have support for a DLP pico projector with a customized interface for the low-res but large screen area.
