The next-generation iPhone will allegedly support a 42-megabit advanced 3G connection when it becomes available in Australia, a senior official at Telstra claims. Having also claimed to have seen the device itself, the anonymous official tells ChannelNews that the phone will "by Xmas" support a planned upgrade to the advanced HSPA+ wireless standard on Telstra's 3G network. This will help drive sales, as the connection will actually be faster than many fixed-line broadband services and potentially the fastest iPhone data service anywhere, the executive asserts. Other sources allege that Telstra has already been testing 3G iPhones, and that its launch is likely to follow shortly after an expected unveiling at Apple's opening keynote for WWDC.
