Can someone help with a problem I'm having. I've been having trouble updating to iOS5 but now my phone is completely unresponsive. When I try and turn it on I get the Apple logo as if it's turning itself on, I then get the progress bar quickly followed by the animated circle going round. Then the phone goes off and starts the loop all over again. I've tried resetting the phone using the home and power buttons but it's doing nothing, I plug it into iTunes and it's not even recognised there. Can someone tell me how to get my phone back to the 'plug into iTunes' logo. Thanks.
