AT&T sent a short SMS to its iPhone customers to announce free access to all its Wi-Fi hotspots. We do not really understand while they only did it now while they are struggling to offer decent data access over its 3G networks since weeks. Indeed, many iPhone users might get better transfer speed via Wi-Fi hotspots, decreasing the pressure on 3G networks. Let's bet than other carriers will soon follow in USA.
