What is Bluetooth?Bluetooth wireless technology is a short-range communications technology intended to replace the cables connecting portable and/or fixed devices while maintaining high levels of security. The key features of Bluetooth technology are robustness, low power, and low cost.
Technically, Bluetooth is a specification for the use of low-power radio communications to wirelessly link phones, computers and other network devices over short distances. The name "Bluetooth" is borrowed from Harald Bluetooth, who was a king in Denmark more than 1,000 years ago (Computer people choose the strangest names!). Bluetooth technology was designed primarily to support simple wireless networking of personal consumer devices and peripherals, including cell phones, PDAs, and wireless headsets.
What is EDGE?EDGE (Enhanced Data Rates for Global Evolution) is a radio signalling technology for 3G mobile networks. It boosts data transfer rates and volumes on existing GSM/GPRS networks by significantly increasing data transfer speeds.
How does EDGE work?EDGE works by improving the signalling interface used to communicate over the radio waves. Typically, EDGE brings three times the performance of GPRS, achieving an average data rate of 80 to 160 kbps per user with mobile terminals supporting 2-4 timeslots. It is great for applications that transfer large amounts of data between a mobile phone and enterprise networks - such as rich email messages that include attachments.
About EDGE Due to its high data transfer rates, EDGE has been adopted as part of ITU's (International Telecommunication Union) family of technologies. Currently, EDGE is standardized by the same 3GPP standardization body as the 3G technology, WCDMA, harmonizing the development of both EDGE and WCDMA.

What Is GSM?Today's Wireless Revolution is being achieved through the GSM family of wireless technology platforms - today's GSM, GPRS, EDGE & 3GSM. It is the basis of a powerful family of platforms for the future - providing a direct link into next generation solutions including GPRS (General Packet Radio Services) EDGE (Enhanced Data for GSM Evolution) and 3GSM. GSM's unrivalled success can be attributed to many factors, including the unparalleled co-operation and support between all those supplying, running and exploiting the platform. It is based upon a true end-to-end solution, from infrastructure and services to handsets and billing systems. GSM is a standard that embraces all areas of technology, resulting in global, seamless wireless services for all its customers. It's all part of the Wireless Evolution.
GSM (Global System for Mobile communications) is the technology that underpins most of the world's mobile phone networks. The GSM platform is a hugely successful wireless technology and an unprecedented story of global achievement and cooperation. GSM has become the world's fastest growing communications technology of all time and the leading global mobile standard, spanning 214 countries. Today, GSM technology is in use by more than one in five of the world's population - by June 2006 there were over 2 billion GSM subscribers, representing approximately 80% of the world's cellular market. The growth of GSM continues unabated with almost 400 million new customers in the last 12 months. The progress hasn't stopped there. Today's GSM platform is living, growing and evolving and already offers an expanded and feature-rich 'family' of voice and multimedia services.
Before You Buy, Please Note:
These GSM phones are NOT compatible with CDMA carriers such as Verizon and Sprint. If you are buying an Unlocked GSM phone and your intended service provider is not among those major carriers, please contact that provider to determine their GSM compatibility.
What is mobile email?Mobile email offers the possibility of sending and receiving email from your mobile device wherever you are. You may even be able to use the same email account you have on your desktop or laptop computer.
How does it work? There are several ways to receive email on a mobile device. These are to do with the application used, and the underlying technology that makes it possible. With web-based email services, a browser is used to access the email interface on the mobile device. With a client-server email implementation, the user interface is provided by the email client, which interacts with an email server to send/receive email messages. This is similar to email clients you may use on a desktop PC like Microsoft Outlook.
In some email clients, such as BlackBerry, email is automatically retrieved when email is received. In other email clients, the user decides when and how often e-mail should be fetched.
