Been having the same problem lately, and Pharcyde seems to as well.
Wifi speed is good (Sydney) : 30 ms, 9mbps DL, 1mbps upload (Speedtest).
I usually only got 300-500 ping constantly before, but I've been spiking from 300 to as much as 20k, then back again, then up again, constantly.
3G seems more stable when there's good reception.
