Will Apple call the next gen iPhone the 4G? Most have been calling the unannounced device the iPhone 5, but recent reports speculate that Apple could end up calling it the 4s (like the 3GS).
AT&T has changed its 4G nomenclature to include devices that previously weren't fast enough to be considered "4G." In AT&T's latest series of marketing campaigns, they have started to call slower devices "4G." The devices that are referenced by AT&T posses the same speeds as what is expected from the next iPhone.
