This has been reported across the web since first reported on MacForums today.
I must admit, I’ve tried it on my iPhone 3GS running iOS4.1 and am unable to reproduce. Perhaps my Service Provider or the Australian Emergency Number system prevents entering anything but triple zero.
When I enter a bogus number in the Emergency Calls view, it straightaway tells me “Emergency Calls Only”.
Which leads to another question.
For Emergency calls, why isn’t as simple as one big button in the screen dialling 000 in Australia or 911 in the US or 999 in Ireland?
It’s not as if individual countries have multiple Emergency call numbers, is it?
