Hello, I just got a new iphone and was trying to disable the EDGE function but when I searched the forum, most advices were to enter any irrelevant text such as "nothing" or "disable" in the APN field.
But then my iphone doesn't seem to have that function? I can go to Settings>General>Network but no option for Cellular Data Network.
My phone is nonJB so I didn't try the 'BossPrefs' or 'SBSettings' option.
Can anyone give me a solution to this?

Thanks! Will try it tonight!
