palmOne - Products - Treo 600 Smartphone:This is a real limitation in a Smartphone. Now that I understand, I can work around it. Both times, I had left a person a message and immediately started using wireless Internet to kill time until they called back. I will use more offline browsing. I did see information elsewhere that the same is true for the Treo 650.
3. What happens if I get a voice call while I'm accessing the data features (email, web browsing) on the Treo 600 smartphone?
If there is an active data connection (you are actively sending or receiving data), then all incoming calls go directly to voice mail. Once the voicemail message is left, you will get an alert telling you that you have a message."
