Mobile devices present the opportunity to enhance our fast-growing and globally connected society improving user-experience through novel approaches for information dissemination through mobile communication. The research community is developing new technologies services and applications to enable ubiquitous environments based on mobile technology. This paper tackles several important challenges such as communication cost and device limitations for development of ubiquitous multimedia applications. And we propose a system for news delivery using a set of wireless multimedia applications. For this purpose we have performed a case study with Apple iPhone s platform featuring two multimedia application contexts namely Web and native applications. The multimedia mobile applications draw on iPhone s assets enabling context-awareness to distribute news improving communication efficiency and setting-up viewing optimizations thus enhancing user-experience. The proposed system is evaluated and validated through a series of real-life experiments on real devices with online full availability. .
