EarthLink to offer cellphone with built-in WiFi for unlimited VoIP calling

CNET managed to pry a few details out of EarthLink about SK-Earthlink, that new joint venture with South Korean carrier SK Telecom they announced back in January to team up on cellphone service here in the US. Nothing about a possible launch date or pricing, but apparently the plan is to offer at least one cellphone with built-in WiFi that would let subscribers make unlimited local and long distance VoIP calls (as part of their monthly plan) when they’re in range of a wireless hotspot and then roam on the wider cellular networks every else.
