Facebook highscore in mobile

Hello,

Can I use Facebook object in a mobile (say iPhone) game?

i.e. ask user to login to Facebook in mobile and then see the highscore among friends, ....

Thank you

I've been able to get the Facebook object to work on a few mobile devices, but with so many varying mobile devices I can't say that it works on all of them. The one's that worked for me were the iPhone 4G, and Samsung Galaxy II.

I'm mostly looking for Android tablets such as Nexus 7.

How can I test if it works?

i.e. should I just put it there and if it works then it works? Or I must do some tweaks?

Thank you

I would do a quick test program and try it out on the device.
