This is my primary gripe with facebook. You'd think that they'd be able to develop a decent mobile app, being as large as it is.
The google+ app works way way way better. So smooth and everything loads quickly as it should. Hell, even the tumblr app I use works better than the facebook one.
Their iPhone app used to work really well. Then, they tried to do some crazy cross platform shenanigans to keep the mobile website, iPhone, and Android versions on the same general codebase. That's when things really suffered and I've read articles saying they're ditching the cross platform stuff and going back to native. We'll see.
The cynic in me assumes since they have no mobile monetization story that I have seen their desire to spend time on mobile clients is low. I find some humor in a firm that trots out how they only hire the best of the best of the best can't field an even half-way decent mobile app.
