I down loaded the latest IOS update, and since then the screen turns blue, the apple symbols appears it turns blue again and finally came up! Now today when I went to register for tickets on WTKR home page, it did it again, and won't turn back on.
All windows are closed each night so I know I 'm not running to many apps @ once!
Call my phone from landline and voice message came up!
The phone will not turn on now, not even press both buttons together
