What is the difference between the Facebook and Facebook for HTC Sense apps? The phone identifies "Facebook for HTC Sense" as an app, but it's no available on the app list to launch and use, thus I have downloaded and installed the standard "Facebook" android app. Additionally, I am having trouble syncing my contacts and Facebook. When using the accounts and sync feature, I am given the option to sync via either the Facebook for Facebook for HTC apps, but doing so with either of them doesn't update any of the information or pictures in my contacts. Even when selecting a contact individually then using link option to select their facebook page, it goes through the motions but then adds nothing.
