Me and my dad have an iphone and I get better signal then any of my friends here with their nokias...I don't know what it's like with US networks...but I have a few friends that have an iphone 4 and they say it never gives them any problems...
for here it all depends on the carrier, the big ones are telstra, optus and vodaphone
all work well inside cities and large towns, but telstra is the only one that works well outside heavily populated areas
