Does iPhone appear frozen or stuck? To reset iPhone, press and hold the Sleep/Wake button and the Home button at the same time for at least 10 seconds. During this time, a red "power off" slider may appear and the screen may go black, but do not release Sleep/Wake and Home buttons until the Apple logo appears. Want to ask. Can we charge through laptop? why not? however the USB port on the computer typically provides an unstable flow of current, and hence the longer charge time. and there have been some debates previously, as there are known cases, in which dodgy USB ports have fried devices, such as thumbdrives et cetera This post has been edited by nokia2003: Sep 2 2009, 09:25 PM

QUOTE(nokia2003 @ Sep 7 2009, 10:27 PM) good thing that i have an appointment tomorrow morning. my only regret is that i cannot erase my data thoroughly before handing my unit over. a few reasons why: 1. iTunes will not detect it. 2. it will not purge into DFU mode. 3. the battery is too low, to erase via the iPhone's settings (and then reset everything) QUOTE(nokia2003 @ Sep 8 2009, 03:31 PM) my appointment for the genius bar was the first of the day (at 9am) and by the time i got there, there were prospective customers lining up already (on a tuesday!) before the shuttle door lifts up! » Click to show Spoiler - click again to hide... « expected solution, of course

PLEASE SAVE MY IPHONE ANYONE. any suggestions are welcomed and thankful! upgrade to the latest firmware i.e. OS3.1.2 that solved my heat problem.
