Today AT&T said that it had implemented a series of software upgrades to improve its backhaul capabilities. The software should provide for a more consistent wireless data experience for all customers. AT&T says that it has six HSPA trial markets up and running, which include Charlotte, Chicago, Dallas, Houston, Los Angeles and Miami. AT&T expects to have the bulk of its network running 7.2Mbps HSPA by the end of 2010. AT&T didn't say anything about HSPA+.
