I just installed the Facebook app but I can't get logged on. It keeps telling me "the email/password combination you entered was incorrect. Please try again."
I know what my email and password is but its not accepting it with the BB app. Any ideas??

Try deleting the app and service book, reseting the curve, then installing again from scratch. This seems to fix most issues in the FB app for a few days at least.

Can the Facebook app be installed OTA? I've only been able to find a link to install it by connecting the BB to my computer and installing it that way.

I just logged on through the Blackberry Browser so FB is up and running... figure I'll wait till the bugs are worked out before I install the FB BB app...

Like David said,
Try deleting it,
Do a battery pull,
Then try reinstalling it.

Oh well...did all that, deleted, pulled battery, re-installed. But it still says my email address or password is incorrect. Strange, no biggie, just thought it would be nice to have.

Do you have numbers or capital letters in your password?

on your bb, do a google search for "facebook blackberry"
the first hit will take you to facebook's bb site

from there you can download the facebook app OTA

Yes, I have numbers and I'm typing the numbers correctly.
