I'm by no means a computer newbie - although I am a new iPhone user. But what should have been straightforward update has killed my iPhone 3G wi-fi and bluetooth Wi-fi says 'No wi-fi' Bluetooth says 'unavailable' I have done a restore to factory, then restore from backup (twice) I've done a reset networj settings I've done a resttore to factory then 'setup as new phone' I've reset settings. I'm now on a full reset - it said it would take 2 hours. Any other advice? It's on O2 in the Uk - could I take the phone to the local Apple store for a fix?
