Who needs 4G? Ericsson is busy upgrading the current HSPA 3.5G to 42Mbps downlink. Some of this speed can be had by simply upgrading the software at the Ericsson base station. Carriers like Telstra in Australia will have an easy time upgrading to this new speed limit. Now we need some devices to be introduced soon so we can take advantage of this new speed limit of wireless goodness.
