I am currently on Optus 3G network in Australia. Needless to say, with Telstra's monopoly on the mobile network, service is limited... everywhere! I am constantly getting the 'lost cellular network' notification... Annoying!
Will changing the setting in my iPhone 3GS, 16GB, iOS4, to 'automatic' under the carrier option (instead of Optus) cause constant in and out of roaming, and increased charges for roaming?
