AT&T's retail store on Wall Street sold its entire supply if iPhones today, which consisted of just 60 devices, according to one report. Barron's Online notes that the phones quickly sold out, but that AT&T offered all those still in line the chance to order a phone for delivery in seven business days, or three business days for an extra $15. The store also ran out of compatible Bluetooth headsets, but allowed a line to form for hours outside that was 2-3 times longer than the number of available iPhones, according to the report.
