The recent update to the Android Market had plenty of people excited about new features to be available in Gingerbread, but it seems like the update may have had some unpleasant side effects. The Appbrain Fast Web Installer feature, which allowed users to push application downloads to their phones straight from Appbrain.com, is now broken due to new security measures. Some naysayers may think that Google is going directly after Appbrain, but in reality, the reasons are much less nefarious. A security flaw that allowed one app to secretly install others was recently exposed by a security company, and the side effect of fixing it broke the Fast Web Installer. This is certainly unfortunate, but hopefully Google will build similar functionality right into Gingerbread.

From the AppBrain team:

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).
