I'm in Ceres at the moment with my wife. I quickly had a look at MYADSL to see what's new.
I'm amazed to see that I get speeds of up to 84kbit/s (10.5kBytes/s) in Ceres. To my knowledge there's definitely no EDGE coverage in Ceres and my Jasjar only have GPRS and 3G.
Virgin Mobile's GPRS speeds are excellent.
What speeds do you guys usually get with Virgin Mobile GPRS? And where do you get those speeds?
