I was at work today and I was playing with my iPhone 3G... Well the springboard locked up so I did a hard reset with the home and power button. When I turned the phone back on it had the restore to itunes logo and "slide for emergency calls" button as well. I was instantly puzzled... When I slid the bar my blue keypad theme was still working. I also noticed for a quick second my lock background came up and then disappeared. So I did another hard reset and everything came back to normal. The main screen came back and it said "iPhone Activated" and I hit dismiss. Has anyone had this happen to them before? My other problem has been, mail constantly crashes after I open it. Could it be that one of my programs or themes is conflicting with it?
