Is there a keyboard available that will hook into the bottom port of the Treo 600? I know about the one, but Palm sells, but I was trying not to spend quite that much. I thought I saw one by IBiz that had a short cord that would connect to the port, but I haven't been able to find it again. The IR keyboards are just out because many times I'm in a vehicle and don't have some place to lay it flat like it needs to be for the Treo to sit upright. My fingers are just a little too big for the keyboard and I'm just trying to find something else. Any Ideas?
