Yesterday, Microsoft has released Windows Phone 7 Dev tools beta and now the XDA developers brings the unlocked emulator for Windows Phone 7 beta.
According to XDA:
“Uou need to pass a VMID to the XDE executable. As follows…
“C:\Program Files\Microsoft XDE\1.0\XDE.exe” “C:\Users\YOU\Desktop\WM70C1-6414-unlocked.bin” /VMID {E575DA31-FC47-4766-853F-018D823B9EE6}
Or you can place the file in “C:\Program Files\Microsoft SDKs\Windows Phone\v7.0\Emulation\Images” with the name “WM70C1.bin” and debug with visual studio and it will launch.
This should help the devs that want to be able to test with the various task launchers with some actual data.”
