Installed Eclipse, the SDK, etc on my laptop (running Ubuntu). Then ran thru the tutorial which uses an emulated device. Next I tried plugging in my old cell phone ( htc touch vogue) which I had installed Android on last nite, and plugged its usb cable into my laptop. Typing "adb shell" gives me a shell prompt on the old cell phone, and it seems to be running busybox version 1.15.3, and linux kernel not bad!
