According to the message from Australia, the 3G iPhone that Apple will use to target next year's market will support Telstra's 42Mbps HSPA + wireless network.
This high speed almost allows the development of unlimited iPhone applications. In 2008, Telstra will begin to provide 21Mbps 3G communication and double its speed in 2009. Back to the US, AT & T will also complete the construction of 21Mbps 3G in 2009.
