Ever wondered why 3G from Vodaphone is so crap? I did, so from Central station I did a ping test on each network one after another. Here is the difference between the latency to an AARNET connected host @ ANSTO. The results speak for themselves.

Vodaphone:

--- 137.157.8.5 ping statistics ---10 packets transmitted, 10 packets received, 0.0% packet lossround-trip min/avg/max/stddev = 97.773/663.878/1901.235/612.384 ms

Telstra:

--- 137.157.8.5 ping statistics ---10 packets transmitted, 10 packets received, 0.0% packet lossround-trip min/avg/max/stddev = 88.699/96.234/141.846/15.256 ms

I think Telstra is worth the extra money ...
