Re: Iphone Signal Problem?
You may have already tried. If not, powering down the iPhone and waiting for a minute or so, and then powering up might help. Before restoring the phone fully, you could try to restore just the Network Setttings, but before doing that I'd try to see if Optus is having temporary problems. Given the age of your phone, perhaps the SIM card is having problem. Optus may be able to help with that as well.
