AT&T's Emerging Devices product development VP David Haight today said at the 4G World expo today that the company might back away from its traditionally high data-only plans and more towards those like for the iPad. While the iPad was successful, most other devices weren't selling that well because of the traditional US carrier model of $60 per month and an emphasis on contract-bound, locked devices. Apple's special plans were better, he told PCMag, since they were not only much less expensive at $25 but didn't force users to pay for service they didn't need.
