Hi, I am living in México and I am using my iPhone here with a prepaid card. However, I noticed, most undesiredly, that EDGE can sometimes turn itself on. In order to be able to turn EDGE off, somebody recommended me to "jailbreak" and then use "bossprefs". To be honest with you, I got really scared when the person said "jailbreak". I have pawned my iPhone in the past. I just don't want to mess up my phone. Is there a way that you would recommend me in order to be able to shut down EDGE ?? Thank you very much, kind regards, igmolinav.
