Think of 1X as a modem. You 'dial up' your internet connection using the 1X 'modem' over the standard cellular wireless voice network therefore while your 1x 'modem' connection is up the phone is busy.

Once you 'log off' (close the Internet connection) the 'modem' disconnects and all normal Voice functions are returned to your phone.

One thing though is to ensure that the 1X connection closes as soon as you close your Internet Browser/Email program. I have little experiance with 1X as I'm in a EVDO area. My experiance with EVDO is that once the connection establishs it stays until I force a disconnect by holding the red end button for about 5 sec.

Can someone with 1X as the primary mode tells us if it will auto-disconnect once it is idle?
