I've been unable to find Facebook in App World for the past two days. It doesn't appear in a search or in the top applications list.

I can find it by going to the old BlackBerry web downloads via the browser.

They may be preparing for the update to 1.5

I agree with dankarlinski, I believe that they may be preparing for the 1.5 update. Otherwise, it really does not make sense.

its just a possibility. but i guess we will have to wait and see

I noticed this as well..could be a sign that 1.5 is coming...although we have seen so many signs...I guess we will see
