It will come when it comes - nothing you can do about it. If your rooted then you won't get it. Which is why I'm not.
Tapping screen as I talk to myself on my Bootstrapped Bionic
Sorry for the diversion but I have actually frozen the updater 2.3.4 in hopes of not getting the update, losing the root and finding the bloatware.
The only complain I have on the Bionic's performance is that it takes a while to change from the portrait to the landscape orientation. But that might be the specific theme I have loaded. And I doubt their update will fix that.
