I just purchased a used XV6700 and am trying to get used to it. Overall, it works well but I do have a couple of problems and a question.

1) It keeps making unintentional phone calls. I thought that I had the phone screen turned off (back to the today screen) and even the device locked (though it is possible I did not do that) and it called my son numerous times. It also called him as I was putting the phone into it's cradle and I know that the today screen was up then. I realize that pushing the center navigation button with the phone screen up will redial that last number, but is there something else that could be causing these calls?

2) Speaking of the center navigation button, it is missing. There is only a center metal ring. It does move but it only opens what ever is highlighted. Is there any way to fix or replace the button?

3) My final question regards wifi. I have it set up to access my home network and it works fine. Without turning the phone off (I have the updated ROM that allows both phone and wifi to be on at the same time), how do I know an application is using wifi and not Verizon's network? For instance, I have also downloaded Yahoo! Go. I want to make sure I am accessing the web through my home wifi connection and not Verizon's over the air network.

Any help on these issues are appreciated!
