In an act affecting owners of 2G cell phones on AT&T Mobility’s network, including the highly visible, and originally highly expensive first generation iPhone, Open for Business has learned that AT&T has been quietly sacrificing 2G signal strength in an effort to speed up the build out of its next generation 3G network. The first generation iPhone was trumpeted by the company as recently as seven months ago; many 2G phones continue to be sold by the Dallas-based company today.
Cell phones, like other wireless communications devices, have certain radio bands they communicate on. While previously the company had been primarily relying on the 850 MHz band that offers a more robust signal, including superior indoor reception, company technicians confirmed to OFB that transmitters for the 2G signal used by the original iPhone and most other handsets, including most AT&T offered BlackBerry and RAZR models, have been shifted to the weaker 1900 MHz band in some areas.
This shift has resulted in customers past their 30-day return policy, but still with relatively new phones, finding themselves stuck with equipment no longer able to pick up signals properly in previously strong coverage areas, even though the equipment itself is without defect.
