no, there is a mobile application to use with Facebook. For that you need to have a phone like a blackberry or an iphone, and you also need a data plan (not the same as a text messaging plan). At verizon, the data plans run 20–30$ on top of your phone plan. now, facebook might allow you to update your status via text message. in that case, you would be charged a text message for each time you send or receive a text message from facebook. on verizon, a text, if you don’t have a texting plan, can be somewhere around .20/message.
