I have rung and asked o2 this question but they won't give me a straight answer. They always seem to avoid then issue if its to do with using an Iphone out of contract!
Anyway, currently i have a HTC Desire, with 500mg data a month. If i put my sim in my old iphone, will the data i use on Iphone come out of my 500mb data allowance on my contract. Or will i get charged extra. Not sure if there are different data types. I know when i had my blackberry the data was not charged the same as with an iphone.
Thanks guys!
