According to a survey commissioned by Credant Technologies each month sees around 10,000 mobile phones left behind in London Taxi cabs. The worst month for phone losses is December as people are more likely to be inebriated enough to not notice their phone slipping out of their pocket. Presumably the reduction in the size of mobile phones make them easier to lose these days.
Many people are lucky enough to be reunited with their phones by a friendly taxi driver. Other will find that the next fare has taken their device never to be seen again. Loosing your mobile phone can be a real hassle and also a cause of concern due to the amount of personal data the average phone contains. If you are a user of pay as you go phones you may loose all your credit as well as your handset. If you have insurance you will be able to get a new handset but what about its contents?
Chances are your mobile phone contains hundreds of photographs, emails and even music tracks that could easily be lost. Even if you have your data backed up at home you are likely to worry about who has your data and what they intend to do with it. If you access social networking sites from your phone its best not to save your passwords unless you want to see somebody else updating your Facebook page. Similarly it is best to log out of applications such as Skype mobile and other IM providers.
The best way to avoid these issues (other than not forgetting your phone) is to keep your phone locked and use a password for access. This also has the benefit of not letting you use your phone unless you are sober enough to put in a password - not more drunk texts! It is also possible to lock or encrypt your memory card so that the data stored on it is safe. There are now applications available which allow you to remotely lock your phone by text message.
