Mobile phones have become a 21st century revolution. What started out as large and bulky handheld wireless devices have evolved into very sophisticated, stylish, feature-rich and compact phones. First-generation mobile phones used to offer only voice over a wireless network. Modern 3G phones allow you to share data and videos along with your voice. You can click pictures using them, record and share videos, play music, surf the Internet or play games. They have connected people to family, friends, entertainment, and business like never before.

The latest generation of mobile phones are called smartphones. Like computers and laptops, these phones have an operating system, memory, and processor. They can run programs like a computer that has expanded the capabilities of a modern mobile phone. You can download useful applications that are available from the mobile device manufacturers themselves in the mobile device developer community. These apps are usually free or cost you a small amount, but they simplify many of your tasks.

Nokia, Samsung, LG, Apple and Research in Motion mobile phones are the most popular mobile brands in the world, with Nokia being the largest seller of mobile units. In India, there are other manufacturers like Spice Mobile and Virgin Mobiles that sell India-focused mobiles. There are companies that are launching specific phones for students and farmers that form a huge segment in developing countries like India.

Touchscreen mobiles and camera phones are all the rage among young people. You can buy a decent cell phone anywhere from Rs 1000 to Rs 70,000. Social comparison shopping sites allow you to compare mobile device prices, reviews, features, and specifications. There are many options, but to enjoy the real benefits, you need to buy a mobile phone after extensive research.
