Hi Mike, Good find! I think that should do the trick alright. And, the Treo 755P has been announced now, so we should have the device ID info for that one soon anyway. Also, I just noticed this article in the Palm Developer Network while hunting for the 755P simulator: "Detecting Treo Smartphones Programmatically" which is article ID 980. To save you the trouble, here's what it says: Q: Is there a way to programmatically determine if a device is a Treo smartphone without having to know the specific device IDs? A: No, there is no API to support that feature. To detect indirectly if the device is a Treo smartphone, check if the Phone Library is available in the device, as all Treo smartphones include this library. I think your suggestion of looking for the HS feature, or my solution of looking for the HsExtensions database are basically equivalent to the PDN suggestion, with the feature check being the easiest.
