    The release of Appleā€™s iPhone was one of the most intensively publicized product releases in the history of mobile devices. While the iPhone wowed users with its exciting design and features, it also outraged many for not allowing installation of third party applications and for working exclusively with AT&T wireless services for the first two years. Software attacks have been developed to get around both limitations. The development of those attacks and further evaluation revealed several vulnerabilities in iPhone security. In this paper, we examine several of the attacks developed for the iPhone as a way of investigating the iPhoneā€™s security structure. We also analyze the security holes that have been discovered and make suggestions for improving iPhone security

    Valuation of innovation: The case of iPhone

    We estimate the private value of Appleā€™s iPhone by observing abnormal stock market reactions to news announcements and patent publications related to the innovation. Our estimate of the lower bound on the market valuation of iPhone is fairly high, at minimum 30 billion U.S. (event day) dollars. We find that patentable technology explains about 25% of that total value. We also find a weak negative reaction among Appleā€™s rivals to the news about iPhone but no significant reaction to the publication of patent documents concerning iPhone can be observed. The evidence suggests that the value of iPhone primarily stems from Appleā€™s management and marketing abilities and efforts rather than from underlying "hard" technologies and intellectual property.innovation, R&D, patent, iPhone, valuation

    iPhone mobile devices are rapidly overtaking the new generation of mobile phones market, especially among the young generation. It is also gaining a lot of popularity among security specialists and fancy gadgets for collectors. The device is considered as a ā€œspecialā€ mobile phone due to its ability to perform multi-operations if not multitasking. It can therefore be used as a entertainment media device, a camera, a GPS, Internet surfing via Wi-Fi technology, Internet Mobile Edge Services, personal organizer, and finally performing as a cell phone with all the usual services including sms, and so forth. However, the difference between the iPhone and the other conventional phones vendors is its ability to store and process huge volume of data which is supported by decent computing capabilities of the iPhone processor. As part of every technology, such a device can be used for legal and illegal activities. Therefore the potential risks from such ā€œspecialā€ technology are not limited to the possibility of containing illegal materials, such as audios and visuals, including explicit materials, images, documents and the possibility of propagating malicious activities rapidly. Such modification can breach or tamper with the telecommunications network authorities and regulations. The goal of this paper is to focus on both the logical and the physical extraction of the iPhone generation one through the extraction of the iPhone flash drive NAND memory chip and also the logical extraction of data onto the second generation of iPhone using various techniques and methods at our disposal

    Is the iPhone an accurate and useful tool for the monitoring of spinal deformity?

    The progression of spinal deformity is traditionally monitored by spinal surgeons using the Cobb method on hardcopy radiographs with a protractor and pencil. The rotation of the spine and ribcage (rib hump) in scoliosis is measured with a simple hand-held inclinometer (Scoliometer). The iPhone and other smart phones have the capability to accurately sense inclination, and can therefore be used to measure Cobb angles and rib hump angulation. The purpose of this study was to quantify the performance of the iPhone compared to a standard protractor for measuring Cobb angles and the Scoliometer for measuring rib humps. The study concluded that the iPhone is a clinically equivalent measuring tool to the traditional protractor and Scoliomete

    When Apple's iPhone first hit the stores it was an epochal media event.2 Apple, long a leader in high-end computers and personal electronics, was poised to make its entry into a highly-competitive market with a new mobile phone that promised groundbreaking technological capabilities in a sleek, ergonomic package. Apple's CEO, Steve Jobs, extolled the iPhone's virtues to an eager press, and, shortly thereafter, Apple's stock jumped dramatically.3 Apple's loyal devotees lined up in anticipation days before the phone's June 29, 2007 release.4 It took Apple a mere seventy-four days to sell one million handsets.5 But some time after the fanfare had settled down, public perception of the iPhone shifted. As consumers began to use the iPhone, the once-beloved phone began to acquire its share of discontents. Consumers expressed frustration in response to 300-page phone bills,6 expensive roaming charges,7 and, perhaps most vocally, to the technological methods Apple used to police its exclusive agreement with AT&T

    How the iPhone Widens the United States Trade Deficit with the People's Republic of China

    Get PDF
    In this paper, the authors use the iPhone as a case to show that even high-tech products invented by United States (US) companies will not increase US exports, but on the contrary exacerbate the US trade deficit. The iPhone contributed US$1.8 billion to the US trade deficit with the Peopleā€™s Republic of China (PRC). Unprecedented globalization, well organized global production networks, repaid development of cross-country production fragmentation, and low transportation costs all contributed to rational firms such as Apple making business decisions that contributed directly to the US trade deficit reduction. Global production networks and highly specialized production processes apparently reverse trade patterns: developing countries such as the PRC export high-tech goodsā€”like the iPhoneā€”while industrialized countries such as the US import the high-tech goods they themselves invented. In addition, conventional trade statistics greatly inflate bilateral trade deficits between a country used as export-platform by multinational firms and its destination countries.sino-us trade; apple iphone; world trade patterns

    Methods: The creator of the app offered free use of their app to a physical therapy clinic. As the app is only compatible with Apple products, the clinic used the app with any patient that had an iPhone. Retrospective review was conducted to determine if differences in patient outcomes were observed. Patients who had access to an iPad or iPhone were considered part of the ā€œapp groupā€ and used the mobile app to reference and report PT HEP compliance. Patients without access to an iPad or iPhone were considered part of the ā€œnon-app groupā€ and received traditional PT HEP prescription and monitoring. Patient data was extracted from patient medical records, de-identified, and sent to University researchers. An independent t-test was used to analyze age and compliance of the app group and the non-app group. Mann-Whitney U tests were used to analyze number of exercises assigned, global rating of change, functional index score, and pain rating. (See pdf for complete abstract
