i was on the inernet, then put the phone in my pocket because i was at work. when i puled it back out, it was on the favorites screen. when i hit the home button, it doesn't go to the main screen. i can look at recent calls and contact at the bottom of the screen, even go to the internet from a text message, but i can't get to the home page. when i hit the home button once on any page, nothing happens. i hit it twice and it goes back to favorites. i;ve turned the phone on and off several times. nothing has worked. any suggestions?
