Just installed MIUI 18.104.22.168 coming from CM 7.0.3 and i am searching the Market app for the Facebook app and its not there?
If you are having problems finding it on your phone, try finding it on the app market from a computer and remote install it from there.
Sent from my OG Droid, fresh MIUI
I found the same issue with Angry Birds. Had to install it through Amazon AppStore in the end.
No idea why it happened, but it did. Could be a glitch with the newest update to the Android Market and their compatibility guide.
Rooted D1, ChevyNo1 1.1ghz mdV kernel, MIUI 1.6.10 ROM. Google voice/Groove IP home phone.
Droid Incredible 2, Tiamat 1.1.5 kernel, Liquid 3.1 ROM. So far, so good!
