ATT’s controversial “Sponsored Data” plan, originally unveiled in January, has been billed as both a cause for concern and a potential boon for consumers, but in the months following the announcement, not a single high-profile company has joined the pilot program.

The store is currently in pre-beta and will be released on Android phones, tablets and iOS
