I have an Unlimited PREPAID plan that throttles at 5GB. The FAQ on tmobile's website http://support.t-mobile.com/docs/DOC-10969 seems to indicate that music freedom is included in my plan. And so I tried using iTunes Radio today and listened to one song. I checked my data first using tmobile app before using the itunes radio app, I had 4488.8 MB and after using the iTunes Radio and playing one song, I checked my data again and it now says 4490.0 MB. So what gives? I turned off my loc services, turned off mail, closed any apps running on background but still accumulating data. What do you think? Am I missing something?
