Other features that may be found on mobile phones include GPS navigation , music MP3 and video MP4 playback, RDS radio receiver, built-in projector, vibration and other "silent" ring options, alarms, memo recording, personal digital assistant functions, ability to watch streaming video , video download, video calling , built-in cameras 1. The first smartphone was the Nokia Communicator [ dubious — discuss ] in which added PDA functionality to the basic mobile phone at the time. As miniaturization and increased processing power of microchips has enabled ever more features to be added to phones, the concept of the smartphone has evolved, and what was a high-end smartphone five years ago, is a standard phone today.
Nokia and the University of Cambridge demonstrated a bendable cell phone called the Morph.

The vibrations flow through the cheek bones or forehead allowing the user to hear the conversation. This is useful in the noisy situations or if the user is hard of hearing. As of , there are smartphones that offer reverse wireless charging. These phones can only be used with a service plan from the same company.
For example, a Verizon phone cannot be used with a T-Mobile service, and vica versa. A multi-mode phone operates across different standards whereas a multi-band phone also known more specifically as dual , tri or quad band mobile phone is a phone which is designed to work on more than one radio frequency.

Multi-band phones have been valuable to enable roaming whereas multi-mode phones helped to introduce WCDMA features without customers having to give up the wide coverage of GSM. This is also true of 2. The special challenge involved in producing a multi-mode mobile is in finding ways to share the components between the different standards. Obviously, the phone keypad and display should be shared, otherwise it would be hard to treat as one phone.
Beyond that, though, there are challenges at each level of integration. How difficult these challenges are depends on the differences between systems.
This leads to real difficulties in component integration and so to larger phones. The radio interfaces are very different from each other, but mobile to core network messaging has strong similarities, meaning that software sharing is quite easy. It has a special mode of operation, known as punctured mode, in which, instead of transmitting continuously, the mobile is able to stop sending for a short period and try searching for GSM carriers in the area.
This mode allows for safe inter-frequency handovers with channel measurements which can only be approximated using "pilot signals" in other CDMA based systems. Initially, the chip rate of these phones was incompatible. As part of the negotiations related to patents , it was agreed to use compatible chip rates. This should mean that, despite the fact that the air and system interfaces are quite different, even on a philosophical level, much of the hardware for each system inside a phone should be common with differences being mostly confined to software. Mobile phones are now heavily used for data communications.
The main limiting factors are the size of the screen, lack of a keyboard, processing power and connection speed. Most cellphones, which supports data communications, can be used as wireless modems via cable or bluetooth , to connect computer to internet. Such access method is slow and expensive, but it can be available in very remote areas.
With newer smartphones , screen resolution and processing power has become bigger and better. Many complex programs are now available for the various smartphones, such as Symbian and Windows Mobile.

Connection speed is based on network support. Later was introduced GPRS general packet radio service , which operates on completely different principle. It also can use multiple time slots for transfer, but it does not tie up radio resources, when not transferring data as opposed to CSD and like. Some phones also feature full Qwerty keyboards , such as the LG enV.

As of April , several models, such as the Nokia , support 3G communications. Such phones have access to the Web via a free download of the Opera web browser. Verizon Wireless models come with Internet Explorer pre-loaded onto the phone. As more complex features are added to phones, they become more vulnerable to viruses which exploit weaknesses in these features. Even text messages can be used in attacks by worms and viruses. A virus may allow unauthorized users to access a phone to find passwords or corporate data stored on the device.
Moreover, they can be used to commandeer the phone to make calls or send messages at the owner's expense. Mobile phones used to have proprietary operating system unique only to the manufacturer which had the beneficial effect of making it harder to design a mass attack. However, the rise of software platforms and operating systems shared by many manufacturers such as Java , Microsoft operating systems, Linux , or Symbian OS , may increase the spread of viruses in the future.
Bluetooth is a feature now found in many higher-end phones, and the virus Caribe hijacked this function, making Bluetooth phones infect other Bluetooth phones running the Symbian OS. In early November , several web sites began offering a specific piece of software promising ringtones and screensavers for certain phones.
Those who downloaded the software found that it turned each icon on the phone's screen into a skull-and-crossbones and disabled their phones, so they could no longer send or receive text messages or access contact lists or calendars. The virus has since been dubbed " Skulls " by security experts. The Commwarrior-A virus was identified in March , and it attempts to replicate itself through MMS to others on the phone's contact list. Now the latest V3. Here is the user manual.
