New iPhone user, and I've been reading about the iPhone 5 going over the data allowance when being used on wi-fi. I've also read that the issue has been fixed. Can anyone verify this( the problem and the fix)? I plan to turn the data on only to check email during the day or to send a business related photo and then turn Data off until I need it again, as I am almost always within reach of a wi-fi system somewhere. My memory being what it is, I'm sure I will forget to tun it off at least occasionally and the last thing I want is a $50 bill from Verizon for sending someone a photo and not turning off the switch.
