My phone died last night, I plugged it into USB connection on computer this morning like i always do when charging. While it was charging i tried to turn it on to check my messages. It did not work so i unplugged it to turn it on, it still would not turn on. I tried to plug it back into the computer and recieved the message "Power Surge on HUB Port, USB device exceeded power limits of Hub port." Now my phone won't even pull up the apple symbol when i push the power button... how do i 1. turn my phone back on, and 2. charge it?
