Softbank May Raise Spending 11% for Network Expansion
Summary (6/30/2007) Softbank Corp., which owns Japan’s third-largest mobile-phone company, plans to boost capital spending at least 11 percent this year to expand its network and catch up with bigger rivals NTT DoCoMo Inc. and KDDI Corp. The company will raise spending to about 432.9 billion yen ($3.5 billion) in the 12 months ending March 2008, from 389.8 billion yen a year earlier, Tokyo-based Softbank said in a financial statement submitted to the Ministry of Finance on June 22. The mobile-phone unit will increase spending at least 26 percent to about 387.9 billion yen, according to the document.Chief Executive Officer Masayoshi Son failed to meet his network expansion plans last fiscal year. By the end of March, Softbank had 29,404 base stations, which transmit mobile-phone signals, missing the company’s own target and trailing DoCoMo’s number of stations by 36 percent.

Aims and Scope
Recent advances in wireless technology have led to mobile computing, a new dimension in data communication and processing. Many predict a new emerging, gigantic market with millions of mobile users carrying small, battery-powered terminals equipped with wireless connection, and as a result, the way people use information resources is predicted to be radically transformed. The International Journal of Mobile Information Systems (IJMIS) presents visionary concepts and stimulating ideas in mobile information systems at both the theory and application levels. The objectives of the journal are to be a source for mobile information systems research and development, and to serve as an outlet for facilitating communication and networking among mobile information systems researchers, practitioners, and professionals across academics, government, industry and students. The journal is published multiple times a year, with the purpose of providing a forum for state-of-the-art development and research, as well as current innovative activities in mobile information systems. The main goal will be to provide timely dissemination of information.

Phone Information
The phone information pages cover many of the phones produced but will not always be up to date with the latest phones due to the large number released. The primary aim of the phone information pages is to offer an archive of information after the phone manufacturers replace a phone and remove it's information from their website. If there are any phones that we have missed let us know and we'll try and get the information and add it.
SIM card
In addition to the battery, GSM cellphones require a small microchip, called a Subscriber Identity Module or SIM Card, to function. Approximately the size of a small postage stamp, the SIM Card is usually placed underneath the battery in the rear of the unit, and (when properly activated) stores the phone's configuration data, and information about the phone itself, such as which calling plan the subscriber is using. When the subscriber removes the SIM Card, it can be re-inserted into another phone and used as normal.
Each SIM Card is activated by use of a unique numerical identifier; once activated, the identifier is locked down and the card is permanently locked in to the activating network. For this reason, most retailers refuse to accept the return of an activated SIM Card.
Those cell phones that do not use a SIM Card have the data programmed in to their memory. This data is accessed by using a special digit sequence to access the "NAM" as in "Name" or number programming menu. From here, one can add information such as a new number for your phone, new Service Provider numbers, new emergency numbers, change their Authentication Key or A-Key code, and update their Preferred Roaming List or PRL. However, to prevent someone from accidentally disabling their phone or removing it from the network, the Service Provider puts a lock on this data called a Master Subsidiary Lock or MSL.
The MSL also ensures that the Service Provider gets payment for the phone that was purchased or "leased". For example, the Motorola RAZR V9C costs upwards of CAD $500. You can get one for approximately $200, depending on the carrier. The difference is paid by the customer in the form of a monthly bill. If the carrier did not use a MSL, then they may lose the $300–$400 difference that is paid in the monthly bill, since some customers would cancel their service and take the phone to another carrier.
The MSL applies to the SIM only so once the contract has been completed the MSL still applies to the SIM. The phone however, is also initially locked by the manufacturer into the Service Providers MSL. This lock may be disabled so that the phone can use other Service Providers SIM cards. Most phones purchased outside the US are unlocked phones because there are numerous Service Providers in close proximity to one another or have overlapping coverage. The cost to unlock a phone varies but is usually very cheap and is sometimes provided by independant phone vendors.
Having an unlocked phone is extremely useful for travelers due to the high cost of using the MSL Service Providers access when outside the normal coverage areas. It can cost sometimes up to 10 times as much to use a locked phone overseas as in the normal service area, even with discounted rates.
For example, in Jamaica, an AT&T subscriber might pay in excess of US$1.65 per minute for discounted international service while a B-Mobile (Jamaican) customer would pay US$0.20 per minute for the same international service. Some Service Providers focus sales on international sales while others focus on regional sales. For example, the same B-Mobile customer might pay more for local calls but less for international calls than a subscriber to the Jamaican national phone C&W (Cable & Wireless) company. These rate differences are mainly due to currency variations because SIM purchases are made in the local currency. In the US, this type of service competition does not exist because some of the major Service Providers do not offer Pay-As-You-Go services.

Culture and customs
Between the 1980s and the 2000s, the mobile phone has gone from being an expensive item used by the business elite to a pervasive, personal communications tool for the general population. In most countries, mobile phones outnumber land-line phones, with fixed landlines numbering 1.3 billion but mobile subscriptions 3.3 billion at the end of 2007.
In many markets from Japan and South Korea , to Scandinavia, to Malaysia, Singapore, Taiwan and Hong Kong, most children age 8-9 have mobile phones and the new accounts are now opened for customers aged 6 and 7. Where mostly parents tend to give hand-me-down used phones to their youngest children, in Japan already new cameraphones are on the market whose target age group is under 10 years of age, introduced by KDDI in February 2007. The USA also lags on this measure, as in the US so far, about half of all children have mobile phones.[14] In many young adults' households it has supplanted the land-line phone. Mobile phone usage is banned in some countries, such as North Korea and restricted in some other countries such as Burma.[15]
Given the high levels of societal mobile phone service penetration, it is a key means for people to communicate with each other. The SMS feature spawned the "texting" sub-culture amongst younger users. In December 1993, the first person-to-person SMS text message was transmitted in Finland. Currently, texting is the most widely used data service; 1.8 billion users generated $80 billion of revenue in 2006 (source ITU). Many phones offer Instant Messenger services for simple, easy texting. Mobile phones have Internet service (e.g. NTT DoCoMo's i-mode), offering text messaging via e-mail in Japan, South Korea, China, and India. Most mobile internet access is much different from computer access, featuring alerts, weather data, e-mail, search engines, instant messages, and game and music downloading; most mobile internet access is hurried and short.
The mobile phone can be a fashion totem custom-decorated to reflect the owner's personality.[16] This aspect of the mobile telephony business is, in itself, an industry, e.g. ringtone sales amounted to $3.5 billion in 2005.[17]
The use of a mobile phone is prohibited in some train company carriages
Mobile phone use can be an important matter of social discourtesy: phones ringing during funerals or weddings; in toilets, cinemas and theatres. Some book shops, libraries, bathrooms, cinemas, doctors' offices and places of worship prohibit their use, so that other patrons will not be disturbed by conversations. Some facilities install signal-jamming equipment to prevent their use, although in many countries, including the US, such equipment is illegal. Some new auditoriums have installed wire mesh in the walls to make a Faraday cage, which prevents signal penetration without violating signal jamming laws.[citation needed]
Trains, particularly those involving long-distance services, often offer a "quiet carriage" where phone use is prohibited, much like the designated non-smoking carriage of the past. In the UK however many users tend to ignore this as it is rarely enforced, especially if the other carriages are crowded and they have no choice but to go in the "quiet carriage".[citation needed] In Japan, it is generally considered impolite to talk using a phone on any train -- e-mailing is generally the mode of mobile communication. Mobile phone usage on local public transport is also increasingly seen as a nuisance; the city of Graz, for instance, has mandated a total ban of mobile phones on its tram and bus network in 2008 (though texting and emailing is still allowed).[18][19]
Mobile phone use on aircraft is starting to be allowed with several airlines already offering the ability to use phones during flights. Mobile phone use during flights used to be prohibited and many airlines still claim in their in-plane announcements that this prohibition is due to possible interference with aircraft radio communications. Shut-off mobile phones do not interfere with aircraft avionics; the concern is partially based on the crash of Crossair Flight 498. The recommendation why phones should not be used during take-off and landing, even on planes that allow calls or messaging, is so that passengers pay attention to the crew for any possible accident situations, as most airplane accidents happen on take-off and landing.http://en.wikipedia.org/wiki/Mobile_phone

According to internal memos, American Telephone & Telegraph discussed developing a wireless phone in 1915, but were afraid deployment of the technology could undermine its monopoly on wired service in the U.S.[2]
Japan's first commercial mobile phone service was launched by NTT in 1978. By November 2007, the total number of mobile phone subscriptions in the world had reached 3.3 billion, or half of the human population (although some users have multiple subscriptions, or inactive subscriptions), which also makes the mobile phone the most widely spread technology and the most common electronic device in the world.[3]
The first mobile phone to enable internet connectivity and wireless email, the Nokia Communicator, was released in 1996, creating a new category of multi-use devices called smartphones. In 1999 the first mobile internet service was launched by NTT DoCoMo in Japan under the i-Mode service. By 2007 over 798 million people around the world accessed the internet or equivalent mobile internet services such as WAP and i-Mode at least occasionally using a mobile phone rather than a personal computer.
As of 2007, more than a billion mobile phones are sold each year, including over 100,000 smart-phones.[4]
