I decided after all the negative talk about the iPhone 4 having issues with its antenna - delightfully referred to as the "Grip of Death", to try this on my brand new iPhone 4 on Telstra - as I expected this issue did not occur - video proof here: http://www.youtube.com/watch?v=8yR7FY0-cqk The issues that did occur in the US / Canada are because of the sub standard networks and poor reliability, unlike Telstra here in Australia. This same grip of death also fails to occur on my brothers iPhone 4 as well. Further proof its a network issue, not the iPhone 4 itself.
