Last night when i was going to bed i plugged my phone up to the charger and it started to update with the newest software which was 7.1.something? and this morning when i woke up my phone was turned off and will not turn back on, when you attempt to turn the phone on it flashes a screen that has a blue dot and a picture of the charging cable and just says i tunes. How can I fix my phone? I am trying to download itunes to my computer now but not sure it will fully work.
