Query: Using EDGE on Vodafone
I have a software unlocked iPhone i've been using for a while now. Its running on a prepay system through NZ vodafone, you put credit on it etc, and can only use the credit you have put on. I spent the credit i have for the month, and am running on $0.00 dollars. Yet whenever i use google maps/safari over EDGE, it works absolutely fine. And i dont seem to be getting charged. At all. This is quite awesome, really, but im wondering why it is happening. Im in no danger of getting a massive internet bill because of the way the prepay system works.
Sorry, i guess this is more of a Network question than an iPhone question. Still, i hope someone knows whats up?
