The facebook app that was originally created for the KIN phones is no longer available for the M models. If you would like facebook on your phone, open your browser and go to m.facebook.com, the mobile facebook application. Once it is loaded, click the star and save it to your favorites, or pin to your app screen, your choice. Once you sign in, the phone will keep all of your log in info until you delete the files/cookies/history and reboot the phone. Same thing goes for twitter. If you select to have it as your favorites, all you need to do is drag your finger down from the top of the page and you will see every favorite you store. From here, you simply click it and go to the webpages you choose.
You can text or use the app to comment, update status, etc. If you would like to upload pictures to your facebook, you can send them via text or email to email@example.com . Make sure you have already added your mobile phone number to your account online before you do this step.
