Well that didn't take long. Earlier today we saw Facebook version 18.104.22.168 available for some in the Beta Zone, and then it got pulled just like that. Nothing is lost as now version 22.214.171.124 is available for download from BlackBerry App World. The new version is showing for some and not for others (it may be device specific?) so we're not totally sure what's up, but give it a go and let us know in the comments if its working for you. Thanks Khalil!
