I pulled down the 2.2 SDK yesterday and noticed this time around that the Launcher2 is now used in the emulator. It got me wondering if I could get it to work on a 2.1v3 Eris. So, I copied the Launcher2.apk from the emulator and tried to install it on my phone, but I get a parse error trying to install it. Anyone else give this a shot or know what I can try?
