All downloads would be limited to Wi-Fi however, as RIM does not want to "over-saturate carriers' networks." GSM-based BlackBerries would be able to download the shows, but CDMA-based phones would not, as CDMA carriers such as Verizon have asked RIM to strip WI-Fi capabilities from their phones so users are forced to use carrier 3G services.
If the rumor is proven true, RIM would have an advantage over other smartphones, most notably the Apple iPhone, which only allows music and podcast downloads from the iTunes store, but not videos.
