So, with Verizon, your friends, or anybody with access to your mobile telephone number, could annoy you by calling your mobile all day long whilst you're browsing the web, thus terminating your connection?
I don't live in the US, thus have no experience with Verizon or AT&T, but surely there must be a way to prevent the above situation?
I wonder if this is a Verizon-specific thing. When Palm Pre released on Sprint there was an option you could select to have calls go to voice mail when you were actively using the data connection. I've never owned a CDMA smartphone of any kind so I am not expert, but I'm a bit surprised you cannot put the phone in a mode that sends your calls to voice mail when you are actively using data.
