Steve Jobs unveils a new version of its iPhone, with support for faster 3G wireless networks and faster phone.
Finally, Apple has unveiled a second generation of its iPhone, with support for faster 3G wireless networks and communication. It is third generation of mobile phone standards and technology. New 3g phone should provide broadband speed upto 384 kbit/s. Currently Nokia and Blackberry phone leads smart phone. I have palm Treo 700p smartphone and it works like a charm.
The 3G iPhone will be released on 11 July and starting price will at US $199 for basic model. According to BBC news:
The new iPhone also comes with GPS satellite navigation built in for location-based services. The iPhone was first launched last year and was criticised for its support for slower 2G networks only. Mr Jobs said the 3G iPhone was “three times faster” downloading content over a mobile network compared to the original device.
Cell phones can be locked using a SIM lock capability built into GSM phones by mobile phone manufacturers. Most network providers (such as AT&T, Vodafone, T-Mobile, and RIL etc) use this capability to restrict the use of these phones to specific countries and network providers. Generally, phones can be locked to accept only SIM cards based on the International Mobile Subscriber Identity.

A little history about modern mobile phone and its inventor Dr. Martin Cooper.
We use mobile phone everyday. I own a blackberry and a Nokia phone. In the 90s the cellphone was a luxury item. I thought it would be an interesting idea to dig out a little history about mobile phone.
Dr. Martin Cooper of Motorola is considered to be the inventor of the first practical mobile phone. On April 3, 1973, Martin placed a call to rival Joel Engel, head of research at AT&T’s Bell Labs, while walking the streets of New York City talking on the first Motorola DynaTAC prototype.
In 1940s Motorola developed a backpacked two-way radio, the Walkie-Talkie and a large hand-held two-way radio for the US military. The same technology developed further and produced the mobile phone that we know today.
In 1946 USSR (Russia) successfully tested their version of a radio mobile phone mounted inside a car.
The modern handheld cell phone era began in 1973 when Motorola invented the first cellular portable telephone to be commercialised, known as Motorola DynaTAC 8000X.
On October 13, 1983, the pilot commercial cellular system of Illinois Bell begins operating in Chicago. The second pilot system run by ARTS in partnership with Motorola begins operation in Baltimore/Washington on December 16, 1983.
By 1984, Washington, DC has two competing cellular providers,
By 1988, many cellular systems (particularly New York and Los Angeles) are already becoming overloaded as the promise of nearly infinite expansion of capacity from cell splitting turns out to be more costly and difficult than foreseen.
The Motorola StarTac was the first phone in the world with Vibrating alert function. It was unveiled in North America on January 3, 1996. StarTACs remained popular until the early 2000s.
The Sharp J-SH04 was the industry’s first mobile phone to feature an integrated 110,000-pixel CMOS image sensor for taking digital photos (camera mobile phone).
By 2003 or 2004 Blackberry begun to take the market by storm. The phone were optimized for wireless email communication. GPRS could provide data rates from 56 kbit/s up to 114 kbit/s. It can be used for services such as Wireless Application Protocol (WAP) access, Short Message Service (SMS), Multimedia Messaging Service (MMS), and for Internet communication services such as email and World Wide Web access.
On January 9, 2007 Apple unveiled the iPhone to the public.
WHERE WERE MOBILE PHONES FIRST USED?
=> United States of America (USA)
These days we use second generation (2G) GSM / CDMA / TDMA mobile networks and phones. Many service providers now looking to create a third generation (3G) mobile network. The most significant feature offered by third generation mobile technologies is the capacity to support greater numbers of voice and data customers but as usual it is quite expensive to roll out. Now, a 4G system is expected to provide a comprehensive and secure all-IP based solution where facilities such as IP telephony, ultra-broadband Internet access, gaming services, and streamed multimedia may be provided to users.
