AT&T will still implement 21Mbps 3G on its network on its way to 4G, the company's Mobility chief Ralph de la Vega said in an interview late Thursday. The provider had late last year said it would skip HSPA+ to make a more direct leap, but de la Vega now sees the advanced 3G reaching "certain locations" before 4G becomes widespread. He didn't yet have information for FierceWireless as to which areas would get the faster treatment.
