"SK Telecom's rapid success in the deployment and uptake of this new generation of rich communications services demonstrates the significant experience gained in their pioneering efforts in IMS-based services.", said Tad Bogdan, CEO of Ecrio.  "SK Telecom's focus on both innovation and quality initially lead them to Ecrio and our partnership continues to produce substantial results.  We are witnessing a broad and enthusiastic movement toward 4G and IMS-based services around the world and this achievement provides both technical and business confirmation of this direction."
