hi, i have a blackberry pearl 8120, and it used to say GSM below my bars
i wouldnt be able to connect to the internet without being connected on wifi, which is exactly what i wanted
now suddenly, it changed to edge (lowercase), and i can access the internet without being connected to wifi, and i really want to get it changed back to GSM so that i wont be charged for data services
can anyone help me get it changed back
thanks
