I don't understand. My iPhone has worked GREAT since I got it in July 09. It is a 3GS 32GB, with most recent firmware. I synced recently, like 2 days ago, without issue. The battery was 90% charged. I went to check it about 30 minutes ago, like I do dozens of times per day, and it is completely black-screened. No logo, no nothing. It is like it is still in sleep mode. I've pressed and held the Home button, nothing. I've pressed and held the button on the top right of the cell, nothing. It's completely unresponsive. I plugged it into an Apple wall charger hoping to jar it back to life like an AED, but nothing- Not even the usual chirp or buzz I get when I plug in the charger to the phone. Any ideas anyone? If I try to hold down both buttons simultaneously in an attempt to restore, what will I lose? Settings? Apps? Contacts? Photos? Thank you!!!
