Is there a list of devices with known hardware-limited functionality? I tried Sleeptime last night on my Motorola Defy+ and got the ”Measurement incomplete” message as Scotty above. I’ve not yet ruled out it’s something in my phone’s settings, but I figured I could save myself the trouble of troubleshooting if you can just outright say it’s not going to work.

*Edit:* Note to other Defy+ owners: Sleeptime works with battery saving and in-pocket detection disabled, and screen set to never sleep on AC power (in Settings/Applications/Development). They may not all be necessary, I just haven’t yet narrowed it down to ones that are.
