OK I know I did it, I just dont know what I did. The home and the search button on the bottom of the screen stopped working (the menu and the back button still work though) I had just turned on the phone and was clearing apps and deleting all sounds or vibrations on the keypads and adjusting brightness and some other settings. I was in the settings/applications/manage applications/running. section and I cleared the data on some apps to gain some memory and I also force stopped I believe it was called "IQ agent" it was running for 3mins so i figured it was not important. It could have also been anything else I inadvertently did. because I swear it was working then 5mins later it was not. So the million $ question is.. What did I do? And even better than that, as I was typing this my wife calls the office phone and says she called my cell and it went to voicemail. So i call my phone and sure enough it didnt ring. Just great. I'm gonna turn it off and back on but even if that fixes it. I would like to understand what happened or what I did.
