I'm writing a program that imports our contacts into the Contacts db on the phone so they show up in the Contacts app, are available for caller id to draw from, etc. I've got it working the way we want on the emulator and the Motorola Droid. When I go to Menu --> View, I can see our application with a check box next to it, and when it's checked, our contacts show up fine.
However, when I try the same thing on the HTC Evo, the contacts don't show up in People, and I don't have our application listed in the View menu. The contacts show up when I do a search within People, and when the contact calls the phone, their contact info shows up fine.
The contacts I'm testing our application with aren't in the phone already ;-) They're special test cases with unique names; that's how I'm able to determine they are actually coming from our app.
I sort of get the feeling this is a HTC Sense issue, but I don't have a way to confirm that right now. If anyone has any ideas, I'd love to hear them.
