I left my iphone on my table this morning in Portland, and it happens to be a sunny today. I am not sure if it is due to the heat exposure or not? 1. I plugged it into my imac since it told me to connect to itunes, which I did. 2. Now the gray apple logo flashes on and off every 10-15 seconds. 3. I tried holding down the home button and the power switch to boot up the iphone but without any success. Any thoughts? Does it have to something with the battery? When I unplug it from the wall socket the logo disappears , but when I plug it back in, the logo comes back on, but nothing else happens. And, Itunes does not recognize it as we speak. But the phone keeps telling me to connect it to itunes.
