either you stick "phone"symbol which is dial pad to your lifestyle page (i have it in more 3 pages), also i have "spb home" mapped to the send/receive button so when i am driving and using gps, one click on the TP takes me to life style page and dial pad is one touch away
+1 for the call buton, however I like to get back to home screen and get right to my contact when gps is driving
