ok, so I installed it, turned it on.
Went on line to appbrain, selected an app and said to install.
Now what? Nothing seems to be happening on my phone.
We're sorry to report that Google has disabled the Fast Web Installer functionality in the latest update of the Android Market. Google is pushing out this update to all devices now, so we don't know how long the fast web installer will still be relevant. (You can uninstall updates of the market to make fast web installer work again, but it seems the update keeps reinstalling automatically).
