Another one with the same problem. Even a third party app would be fine for me... Any suggestion?
Nope, the issue is between Google and Facebook, so we won't see contact sync fixed until Google and Facebook make an agreement or until a custom ROM fixes is. I forget the whole story, but I think Facebook doesn't use Android's contact API so when you sync Facebook contacts with your phone they all stay with Facebook and aren't stored locally on the phone. If you uninstall Facebook all your Facebook contacts go to. Google doesn't like that FB doesn't let you control and keep your FB data on your phone so they revoked Facebooks access to the API.
EDIT: heres an article about it: http://www.engadget.com/2011/02/22/google-disables-contact-sync-in-facebook-for-android-only-nexus/
Facebook contact data will continue to appear within the Facebook app. Like all developers on Android, Facebook is free to use the Android contacts API to truly integrate contacts on the device, which would allow users to have more control over their data.
You sorta proved my point. More or less its not compatibility with Android 4.0 but its the Nexus S. Once again Facebook will have to upgrade the application in order to make it compatible with the Nexus S. Only difference between what I said is instead of Android 4.0 its for the Nexus S and Galaxy Nexus
Friendcaster is not allowing me to login (whitepage)... Is it really compatible with ICS?
