Hi can anyone help me i have an iphone 3g bought new from the o2 store a year ago decided yesterday to update it to the new 3.0 os it was working fine and fully charged when i connected it to my pc (windows) i downloaded the update no problem and then proceeded to back up my phone at about 98 / 99 % it said my phone was not connected and i needed to re connect it. It was still plugged in but not registering on my pc anymore now i get one of two screens on it 1) the battery icone and plug pointing to a lightning bolt or 2) occaisonaly it shows the itunes picture and plug. it does not charge either at the wall or via the pc yes ive tried to reboot it but it does nothing i get no apple logo cant even make emergency calls help please
