Yes: Optus provide the slowest network for the iPhone, and the worst 3G service worldwide, a survey has revealed.
Wired.com have published a survey showing that Optus has the worst download speed for the iPhone and the 3G network out of all the carriers in Australia.
The survey has also revealed that Australians get the slowest download speed for a 3G network. Download speeds for the average Optus user were also found to be twice as slow compared to other carriers.
iPhones haven’t had a smooth ride on the Optus network. Their plans proved to be the most popular choice for customers but the value for money dropped off when the Optus network failed to deal with the influx of users. Attempts to update the network to cope have struggled as well, with the patches being plagued by bugs rendering Optus iPhone users unable to access the telephone network several times.
