This mobile phone is a durable yet simple GSM mobile. It targeted developing countries and users who do not require advanced features beyond making calls and text message. The 1100 cell phone was one of the most popular cell phones in the world for a few years, with over 200 million units been sold. It was also the best selling consumer electronics device in the world, beating Sony’s Playstation 2, Apple’s iPod and Motorola’s RAZR. In early 2009, it has been in the news that due to a firmware flaw, a batch of phones produced in a plant in Bochum, Germany can be programmed to receive messages directed to a different phone number. This flaw was brought to authorities’ attention after some phones were sold for over $32,000.
