Facebook for iPhone / iPod touch now iOS 4 compatible

We'll get right to the point: the Facebook app for your iPhone / iPod touch is now drinking the iOS 4 Kool-Aid. Fast app switching, high resolution icons (better than the one seen above, since that's pre-update), Korean / Russian localizations, and... that's about it for now. Maybe background image / video uploading is on the list of to-do's, but at least it won't look quite as pixel-deficient on the home screen next to Twitter.
