If you find having to log in and out of different social networking sites on your iPhone a tedious task, you might want to check out the Pinger Phone. The Pinger Phone is an iPhone application that lets you stay updated with your Facebook, MySpace, and Twitter friends. After installing the application, you will be asked to enter a unique user PIN as well as your account details for any of the social networks or messaging clients you’d like to use. It automatically downloads all of your friend’s recent Twitter tweets or Facebook status messages. It pulls your entire contact list and you can use the application to directly dial anyone. The reviewer stated that with the amount of functionality the Pinger Phone has, it can replace your actual phone application. On the other hand, it has room for improvement, such as not being able to recognize duplicate entries and not allowing the user to update his or her own Facebook or Twitter status using Pinger Phone. Nonetheless, the Pinger Phone’s ability to keep you updated on all your social networking sites using a single free application is indeed worth checking out.
