I'm having two problems with my new iPhone 3G (First one wen't back due to random vibrations) 1) When listening with headphones (Apple or other brand), the music will randomly stop or stop playing. I'm not touching the screen at all. 2) Sometimes, screen will get stuck on the phone screen (Favorites, recents, contacts,keypad, voice mail) While I can click on any of these and it will take me to that screen, the home button is unresponsive. The button on top to turn the phone off is unresponsive too. Only way to get out of it is to reset (Hold home and top button). Have latest software. Anyone else having either of these problems?
