Hi everyone, there is a new data plan of att prepaid service and it just began its service from 1st October. I also put this service on my Iphone 4, but the data doesn't seem to be working right now..... Does anyone share the same problem? I don't think ATT has right to block this service for prepaid iphone user if it is so.. or do I need to set something up for the data? I turned on 3g data and cellular data.. Thank you! have a good weekend.
