Yesterday, I have finally solved that problem with an iPhone application. What is so nice about this application is that it is FREE. Go to your iTunes Store and search for the application Duo (Easily update Twitter and Facebook). Once installed, enter your Facebook and Twitter credentials. Make sure to allow permissions.
As shown on the picture, it will indicate if your Facebook and Twitter accounts are logged in. To update both Facebook and Twitter, just type your status then click Update FB status and Update Twitter. The buttons will have the check mark if it has been updated.
Cool and easy right?
