AT&T to allow app developers to pay for your data

If the Wall Street Journal is to be believed, and there are few more credible sources in the media, then AT&T will soon be unveiling a service that allows for app developers to pay for data used by their apps.  In a smartphone market where apps are becoming more graphically complex while most carriers are cracking down on data usage, this would allow the user to use the app as often as they'd like without fear of their data cap.  With Verizon offering a data-tracking widget on their Android handsets and Google building a data manager into Android 4.0, this is a very real concern for many users out there.  This new model would give app developers an advertising advantage with customers who are worried.
