In August all major networks started charging for data usage(from phone calls to music to app usage) for anyone who bought a phone that allowed those 3 things(yes, even if you got the unlimited data package) from August on, so say you bought an iPhone in July, you wouldnt be charged for app usage or phone calls or music, but if you bought an iPhone in August you'd be charged for all that. I bought my iPhone last January so all my data usage is free(thank god).
