Hi - I'm currently on holiday in Sydney, Australia with my AT&T iPhone 4. But, all I get is "No Service". I also have an AT&T Blackberry Storm, and it is getting full bars on 3G on the "Yes Optus" network - but the iPhone gets nothing. Our Family Plan appears to have "Standard International" roaming enabled - so what's wrong?? Why can one phone on the plan get service and send/receive messages, but the iPhone 4 can't??

It should be picking up the 900mhz GSM band, but perhaps not - do you have "3G" turned off under settings/general/network?

"Enable 3G" is set to "ON", Cellular Data" = "ON" and "Data Roaming" is also set to "ON". It will eventually (after a long time searching) see the local networks in the settings list (vodafone AU, Telestra Mobile, 3TELSTRA, YES OPTUS), but it won't provide service to any of them.

Try resetting network settings in Settings! To do this; Settings > General > Reset > Reset Network Settings

Nope - no change after resetting the Network Settings. We leave Sydney tomorrow, maybe it will be different in Melbourne - although I really doubt it...
