I was just wondering what GPRS is? Especially when it comes to using Iphone. Iphone basically connects with WIFI first, if that's not available it goes to 3G then Edge and the GPRS? Do we pay for GPRS and is it something different from Edge?
If I see the small 'o' for GPRS and I try running the browser or any other service, it says not connected to internet. Is that good enough to know that GPRS is not working? I don't want mega charges on my plan for using the GPRS without knowing.
I made sure 3G and Edge are already off, but I'm a bit concerned about GPRS. Please help.
